I don't mind this cartoonish feel, this is interesting. And I think that "curved" style drawing gives that cartoonish touch as more as the digital coloring.
This is a small tomb I made when my rpg groups GM diden't show up and everyone still wanted to play.
The background was just a small tomb that was the resting place of a former lich king.
The tomb is poorly made as he made he undead minions dig it out.
I am currently remaking it on my computer, but it still have some way to go.
So far I actually like the hand drawn more my self. The colorised computer version is sorta.. cartonish looking.
But I am still working on it.
