turn raytracing off, it makes it look like a peice of shit, and what you called shading I called a very low opacity airbrush, and you have to make something on the side of the feet and the front and back, it's 512 so it should be pretty easy.
And, the side of the torso's look kinda bad to me, like they dont belong there but should look more natural and look like it's coming from the top of the armor or something
