This looks good to my untrained eyes. Seriously though keep at it. and if you can seek out Bocodamondo. He is really good at the whole bit. He may help more with the shading techniques than I can. Or Reit9. Either one. I think you're doing things fine. Might could try a little darker hue for shading is the only thing I can offer. Try some other poses and lighting combinations. Nice work. Please post more.
