It's for a game. I'm using NES pallette. I'll see what I can do about the trees, I really don't like how they turned out.

 

The shading doesn't seem right. I can't make it look natural if any of you could give me some guidance I would appreciate it.

If you're going for the goofy low-level enemy look the first version almost got it down, but not to the extent where I know that was intentional. So whatever direction you're going for you need to push that further and make it clear.



Here I made 2 quick variants. Aiming for a more menacing medium-level enemy, although I'm not sure which of these hits that goal, hopefully they demonstrate ways you can take this. Notice the general action, the shoulder tilt in relation to the hip tilt, and the facial expressions. You want this stuff to read instantly in a sprite, and again it depends on the direction you want.

It's will be used for the for the first level area.
