Good, but needs more to focus on
This is a well drawn picture overall, but the most important thing missing (imho) is something in the foreground to focus on. Now everything is really blurry. Maybe you should draw a scavenger with a sharp outline, wondering what's left in the city for him.
I like the way you used your colors, they suit your drawing.
Is that a moon in the background or just a really weird mountain.
Keep on drawing :)
