Getting serious on designs

[Terminal Devastation]

After scouring the SNES, GBA, and arcade sections of TSR, and just roughing out
several poses, I found two I liked (There's surprisingly few spear users with interesting poses, so I had to resort to staff users).
I'm not quite sure out the balance works on the first pose, and I'm not sure how to declutter and clear up the second.

So... how do I make these better?
