Nahhh this is way too gorgeous to be scrapped, I always enjoyed looking at your pixelly art (jdfh I never said anything before because I was a wierd lurker back thennn) The details and effects you put in it are always fantastic, the clouds look really nice, they're a nice realistic shape and not all puffy cotton candy shapes. The dust is really fitting too, aaah your doodles have such crazy detail put in. It's fun to see the different styles of this adorable little desert boy, crap, I wouldn't be able to convert a 3 dimensial looking boy and pack him and that deserted city wreck into a pixelish piece.
This looks really cool! I always liked pixel-esque artwork that's not just used in sprites, but I could never really do it right myself. The sandy tone really gives off a mood of either an Armageddon aftermath or a sandstorm. Either way, really good job!
