I never did beat the game all the way....
Regardless of what I say, your artwork is superb, only real issue with me is that the eggplant bugs me, by which I mean it doesn't appear to have the same texture as the rest of the image. Well that, and the Hudson Bee, but the bee (being a logo) is understandable.
With my word being my oath, I truly do love your piece, and it deserves more than a 4.5, indeed it does, not beyond a 5, rather a 4.8, as there are still some areas (mostly the outlines of the two characters) that could still use some more work to fit with the background and the rest of the image. The Hudson Bee, in addition, I feel is a little too much and potentially clutters the image's simplistic style, though I could very well be wrong. Then, I would without a single doubt give this beauty its well deserved 5/5.
