Character needs help

[Raider]

There is something about him (maybe his legs?) that I can't put my finger on. I really like the face so I don't want to change that but it's got me stumped...

[Technocrat]

It's a good face, I agree. It looks a little like he's leaning backwards, perhaps his head is too far back? Or is this the intention?

[Dualnames]

His/her hands are too stiff. Like he's marbled or something..other than that the shirt feels a little empty but that might fit the character so I'll leave it be.

[Raider]

I've tried to loosen them but the I can't seem to get it right. What do you suggest for loosening the arms? A gap between his shirt and arm?

[Ryan Timothy B]

Just bending the elbows slightly should help it from looking stiff.

The feet being straight with the ground while the character is on an angle, make him look like he has one larger leg than the other.

His/her hands are too stiff.

You saying that is an obvious critique against the sprite.  And yes, I was confused too.
It's very hard to determine whether it is a male or female.  The face gives off a large lady look, while the body looks like a large middle aged man.
