*sniff* looks like an rthro package

I mean, it's good It's not easy to draw, there are some aspects I thought you could improve but I'm not quite sure about it, so take it with a grain of salt if you're interested

About the perspective I'm making an assumption here: The arm on the right is extended sideways Even though, yes, the upper arm is thicker from the side than from behind, I think the upper arm on the right appears a little too thick The viewer is below hip level, maybe on knee, level. So the belt should be more "round", i think it's too straight for that angle. The hand on the left gets pretty big - no problem with that - it's because you chose a small "focal lenght", which results in big size differences. It's a cool effect but hard to consequently draw over a whole image, that has to be constructed. So, to retain that interesting perspective with low focal length (left arm), you should draw the right arm smaller. The overall proportions are correct, but just smaller, and the hand on the right should be way smaller than the hand on the left. Shoulder width is ok as we have the problem of "V shape from underneath" -> it evens out. That's okay. I would fix the shape on the shoulder plate on the righ
