hola senor opacus. this is pretty much a color edit. your colors right now are a bit dull and uncontrasted. so I upped the contrast and added some warmth to it. I might have exaggerated colors a bit much but it's to get a point across. also some of your muscles seem to be made up in some areas, as some of the shapes are a bit wonky. your outlines need to be worked on too but you can do that after finalizing the rest of it really.
Thanks for the edit senor Alkaline
I agree that some of the muscles seem wonky, but I've looked up alot of references, charts of muscles and all that and I really don't know how to make it look better then this.
I've fudged it around alot and changed his arms almost every save I made, but it just doesn't seem to get anywhere.
I tried something again but it probably still doesn't work.
I can't agree with your colour edit though. I think the colours work as it is now. Warm colours really don't work on this in my opinion. It is after all, a homacidal, genetically enchanced, knives instead of arms maniac.
And giving it warm colours takes away the entire cold feeling I want him to have.
