Nice use of colors. Good sence of flow with the water fall. You may want ot soften the edge of the moutain on the right side curve by the tree. Like the concept of the chains holding the supended island.
All n all very good designs.
Thank you. I played around with concept of suspending a chunk of land with chains a week ago for my last project but It didn't have what I needed for that project so I scrapped it. Since this week's project was about Arial Perspective I decided to give it another go. I'm happy with how it turned out, though there are some obvious mistakes that I made that I didn't notice at the time (like the mountain in the background that you pointed out and the waterfall having a weird bend to it on the left of the big tree).
