If we actually cared about his name, the collective efforts of the entire community could have him tracked down in about 2 minutes.

Your drawings are very 2D-ish.

You need to had depth by shadowing the drawings.

I promise I'm not trying to be mean but here we go:

• When you post your artwork (or at least when you post something that is supposed to look finished), clean it up a bit.  It shouldn't look like someone smeared crap all over your piece of paper.
• Learn perspective.  Start with city blocks and move from there.  Set your point of view or reference and stick to it.  Seriously, it looks like the robots arms are coming out of his pecs.
• I actually like the robots feet and legs.  It makes it looks like you've got some sort of character style going on, but I think that's only by chance because the other two characters don't have it.
• Grab a cardboard tube or broom or something long like that and try to hold it like your robot his holding whatever that is in front of a mirror.  Take not of how your arm is positioned.
• The character looked like he was directly ripped from DragonBall Z actually looks decent because he isn't in the same boring position as all your other characters.
• The female character just looks sooooo flat, there's no depth what-so-ever and I don't know why
• The female just looks...long.  It's like you took something with normal proportions and then stretched her out.
• Take or find pictures of hands and just draw them.  Keep drawing them over and over in different positions.
• Females have breasts, you added the bump to show she has them but then she doesn't actually have any.  They don't have to be anime silly big but you get the idea.
• This looks like a Dragon Ball Z ripoff but with robots.  Removing the star from the title alone would go a long way in getting rid of that comparison.  Without that star I might not even immediately think the baby thing is a direct rip off of the one DBZ character.
• Before you spend a lot of time figuring out how to market your title and brand your name all over it and the fancy title, work on making it actually good first.
• Buy one of those wooden pose-able figures and just draw that.  Keep drawing it over and over in every position imaginable.  Once you get good at that, add a body over it.

All-in-all, it's still just bad.  It's obvious you've been trying to work to make yourself better but when your learning wrong it's not going to matter no matter how hard you work. 

DON'T SKIP TO THE END, LEARN THE BASICS.

Super-blunt, and there's another thing to add.

Color!

Also, what the hell are you talking about twesterm. Nothing reminds me of DBZ, except the star which is a stretch. And there's only been one on-screen baby that I can think of, and that's Trunks, and I certainly didn't attribute the baby in his drawing to Trunks.

I can't remember the names for the life of me but it's the friend of the 3 eyed guy, the albino baby kid.  Once you see it you can't unsee it.

As for color, they're sketches and they don't need color.  Color doesn't always help, things like shadows would help, but color isn't essential.

Also, I forgot to add, stop adding theARTIST to all your drawings.  If you had a name like twesterm or dtewi it would be fine, but when you call yourself theARTIST, you should be an artist (unless you're being ironic, which I'm sure you aren't).  Adding theARTIST just makes the picture laughably bad and completely open to all sorts of nasty criticism.

-edit-

Chiaotzu, that's the one!

With a mixture of the baby trunks hair the Prof posted

@twes

haha just noticed that

Chiatzou and Tien?

Chiatzou looks nothing like that kid really. But, it's probably been like 15 years since you saw it.

And if it's a cover for a book, it's ridiculous for it to have no color.

How much screentime does Trunks get anyway?

would your favorite animal be a liger by any chance

side note: went to Arts high school were I majored in art, wish I could post some of my pieces....... I was pretty bad ass

This may sound weird (depending on your age) but draw scantily clad people to learn how anatomy works. The more skin you see and the tighter the clothes, the more you'll learn how muscles flex, bend, and pivot around the skeleton. SI's swimsuit issue or pictures of male swimmers are good places to start. Not only are the people in those magazines close to naked but they're also very toned and/or ripped so you can see how musculature works.

Don't feel awkward about it; if you're going to learn how to do this correctly (and later go on to study it in college), nudity and the human body is something you're going to have to get comfortable with.

Other than that, keep practicing.

PS. to learn how to draw, do NOT study other drawings unless they're anatomy books (such as the great line of Burne Hogarth reference books). Learn how to realistically draw the human body and then interpret it into your cartoon/comic style as you please.

PPS. It is REALLY SHITTY to make fun of the OP. At least he's trying to learn a skill and create something with it. WTF are you doing with your days other than sitting on a fucking couch playing a goddamned video game that somebody else created? Cut the kid some slack, for crying out loud. At least he has the balls to get out there and try.
