Well, so far I've hacked quite a bit of Megaman X's sprites in Megaman Xtreme, and now I'm trying to get a better mindset on extracting and compressing so I can easier edit sprites that don't show up in Tile Layer Pro. I also want to learn text editing as well, but... I'll ask when I get to that.
I suppose you want a few screenshots.

I'm not too shabby at sprite work, but I'm mostly just good enough to get by. Haven't done anything really fancy yet.

This is MegaMiraj firing off his gun. As for how the graphics look, that's mostly sprite scaling effects that happened to the original sprites as well, nothing I did.

You can run MegaMiraj, but you can't fly!

This is where spriting gets a little tricky. Since the sprite constraints won't let me draw the ears any bigger, I had to make due. Also, it took me a while to find the helmet corner piece for the aerial shooting sprite. ...I think I might need to find it again, though, so I can fix his ear.

Last one. Megaman had just defeated Magna Centipede (Which will be called Ninja Echidna after the granddaughter of Gaia) and is throwing his fist up in victory. And... I'm not going to lie, this sprite came out ugly. I was kind of a hard sprite to edit, actually.
(Note: Magna Centipede is a total pantywaste in Megaman Xtreme. ...Although he wasn't all that difficult in Megaman X2 to begin with.)
