There is a very strong balance of darks and lights. I wish that the Metal Slug text was curved to the side at a 3D angle, as that would make it look more dynamic. Additionally, I think the screen could be a bit wider because the tank feels almost claustrophobic in the scene and doesn't have enough space to breathe.
Perhaps it would be better if the tank were moved more to the middle because I feel that the negative space between the foreground and background creates a sharp edge on the side, which contrasts poorly with the roundness of the tank.
Additionally, the clear distinction between the background and foreground is also a strong suit of the piece.
