Nice MK you got there Shea. IMO, he was your hardest character to beat 
Though you could work on using Dtilt instead of Dsmash more often. If you can't gimp your opponent then Dsmash is your next big KO thing whic means your going to want to try to save it to lower SMN. Also more a bit glide and whorenado. Nair is a great of stage gimping tool. There are other throws besides down throw, so try to use the others as well because people are just going to DI away from anything out of your Dthrow if they know you are going to use it.
But other than that great job :D Though, I was getting REALLY annoyed whe I kept choosing Yoshi and my counterpick stage was being ignored >.>
