Let's see, coloring wise I think it's quite well done. I suggest that you use some references for the anatomy, for instance the colar bone should be higher. Also the shading is a bit off, the light source seems to be fairly neutral on the chest area, however on the neck it seems that the light comes somewhere from the character's left side. So yeah keep that in mind
Thank you very much for the feedback! Yea, the collarbone needs fixing as you said. Though, when I was looking at references, I saw some lower like that, so I was thoroughly confused. The light is coming straight on, but since his head his turned slightly towards the right and with elements there, there are those shadows. But yes, it needs further improving on them. Thank you once again for taking the time!
