I am developing a school curriculum using a pixel theme, and would need help designing 10 detailed and colorful backgrounds roughly 1980x1024 of the following:

Cavern
Valley
Cloud City
Palace
Volcano/Desert
Beach
Snow
City at Night
Outer Space
Distressed Planet (Think Apokolips from Superman)

These background would be featured in our free books and videos going into classrooms, and would give you credit on every piece of work. The artwork style would be a cross between Sonic the Hedgehog and Kirby
