I know there are a number of drawing apps for 3DS and am interested in getting some for mine, but I need a few details and it would be nice if any of you guys knew anything.

What I'm looking for specifically is something that makes good lineart. Specifically, any 3DS drawing apps that would allow me to upload a drawing from the SD Card and go over it in the app to make digital lineart, similarly to what I already do with my phone:

Also, are any of them worth it in the first place? Or should I just stick to what I have for now and take the long route in waiting for a tablet (it would be a long wait)

Also, I have a 3DS now, since September. Forgot to make a big post about that, though I guess I'll make a thread and all the games I got later. It's nice finally entering this  Gen.

I'd talk to Smeags about this: he's the go-to drawing master for the 3DS.

Oh, well thanks for the suggestion then.
