In the skull (digitized, also you're avatar) has lines that appaer to be from scanning and using a paintbucket, in the mouth and around the eyes, or if that was an accident - but it looks good with the lines there, and somewhat intentional. Thats no critique I'm just asking, because if it was an accident I'd still leave it. Gives it a stylized look. I would even add a black background and create the same lines outlining the skull. Then it'll look really stylish.
However in you're treasure chest there are some white spots. Such as next to, on the left side, of the lower skulls' teeth. The brim of the treasure chest right there, and some spots along the darked areas elsewhere. I'd fixe these, just makes things look less hashdash.
The Treasure chest looks good, otherwise, except the dimensions seem off. It appears we are looking up at it, but the skull seems flat and dimensionaless. Adding, even if a much thinner backing/side to it would clear that up. Then I'd have nothing to say lol.
Keep it up, and share more. I still really like the style of the chest.
