The muscles of the character are incredibly well sculpted, especially those of the back. It really resembles those of a bodybuilder, so great job on that ! Oh and the overall piece is just amazing too (good job on the pants )
I can use tineye then. If you don't know, you can upload a picture, or give it a link to a picture, and it'll find sites that have the same picture but in different sizes. This way, if you want a picture as a wallpaper but it's too small, you can get it supa-sized sometimes. It doesn't have every site, but it has a lot of them- most pictures I look up return with results.
