Looking good although theres few spots where you should have used different dithering techniques, such as that guy/zombie's skin and whatever rocks and wall there is. That "light-line" on top of the box looks bit jagged, some anti-aliasing wouldn't hurt there and in some other rough spots. Take the challenge few steps ahead and restrict your palette in the future. Dunno if I'm wrong, but it seems like you used quite alot unnecessary colours here. Applauses for pixeling a piece in this huge resolution though, it costs patience and labour of love.
