Could have used more work Dogmeat. There's spots around the edges where AA is needed, the eyepatch is pitch black when it could maybe use some lighting.. the color and source of the light feels off, and there's vertical breaking effect shading on the nose. The eye that is exposed looks less refined and you need some AA on the eyepatch thread. The blue in the background is too dark to be meaningful. The candycane is sharp and fakey looking, like it's a glowy reflective metal sort of thing. The blue drool should probably be black or much less saturant to match the lighting in that area. The general composition of the work is good. I like how the hillside rolls up. The moon is neat, but seems too cartoon like in style compared to the head. Palm trees don't look quite right... could use more leaves.
Might be alot of critique, but I think that this could have been better.
BTW, I did a ZX Spectrum version of the Dogmeat piece!
