Help with my sprites?

[WonderPup]

I've made some changes to the ogre. Before, his hands were done incorrectly. He looked like he was on an exercise machine or something. I gave his arms what I felt were a more natural angle.



The problem I'm seeing right now is that his arms look backwards. I've played with it a lot to try and correct, but I'm not sure how. Does anyone know why his elbows appear to work the opposite way?

Regarding adding more frames, I've posted a question on the other site to see how many animation frames are allowed in the program (RPG Maker VX Ace) that many of the people over there use. I'm still waiting on the US release for it, so I don't have the answers myself. If more than three are allowed, I will add more frames in.

You all mentioned it needing more contrast. How can I achieve that without having the sprite turn into an eyesore? I keep playing around and adjusting the colors, but it always comes out as being overly- or under-saturated. The base color is a green, and I pull that green toward a yellow as it lightens. Is the problem that he is too green?

I'm also working to incorporate highlights into the slime. My design has him looking too opaque.

Thanks for all the input!
