I like your lines and gestures.
As for color, you need to take care of your contrast opportunities. For example, on the drawing You have a little U or drop shape on his chest formed by the hair. On the color one, it was lost. You can achieve contrast and the sort of crispness you get from lineart by building up gradients and killing them quickly. BAM, you have an edge (which will attract attention so only do it on places that are worth it.).
Jamen jag tror att han skäms, och har gömt sig. Vårt universum det är en av dom otaliga spermasatser som Herren i sin självhärliga ensamhet har runkat fram för å besudla intet.
