Just Jumbles

A landscape of Jumbles Island. From right to left: Sunland, the land of the summer, Windland, the land of the autumn, and Snowland, the land of the winter. Do you like the colors used here?
I made it large, so you can zoom in and see the details! Tell me what you think, I would love that  


I made it look really cool thanks to the brushes of this guys:

If you have Photoshop and you like drawing and painting I recommend to you to download those brushes; really helpful!
