NES-style Utsuho Reiuji sheet

I'm not sure I'm 100% with how this sheet came out. This is kind of an "on a whim" sheet, really. But, hey, it could work for something.

First row:
Size comparison with Mega Man, in addition to a standard shooting sprite, and a grayscale palette for some reason. (I don't know, maybe when something really big explodes?)
Second:
Raising the arm cannon up, basic wing/leg positions for flying pose.
Third:
Shooting while flying, another shooting pose, a defeat pose, as well as two things that could possibly be balls of nuclear fuckyourshit.
Fourth:
Silly things! Walking poses, maybe? And, an extra sprite just because I wanted to fill it out a bit more.

I may add on to this sheet, actually. But yeah. Anyone else I should sprite? Hmm...
