not really a mockup. some areas look good, others look like rushed blobs. is the font handmade?

Thank you for the comments. I didn't much like the explosion but I dont know exactly what to do to it to help it.

Nice texture on the sand dunes, its reallyclear where they are :> the cloud part of the explosion could do with a bit more puffiness so it doesnt look like a peanut, also the clouds in the background dont really looks pixelled rather drawn with a dragged out pencil tool
