It's Peter Pan and Lost and Cast Away and Pirates and Australia and the Maldives and Jurassic Park and fun in the sun with monkey servants. I think it's fabulous that by not making it 'fantasy setting 2', by setting it as 'imagination', it became all those things to me at once. Fascinating. Good colours and texture, too.
I Would love to see this scene at dusk with blood red highlights in the sky and a campfire on the beach, that is the only way this could appear more awesome!
One thing, and im not sure if its just my eyes or my laptop screen but those turquoise flowers on the top of the branch in the top left of the image, just seem off to me, they clash with the sky too much, i feel these should have been either a orrange or a white flower. But other than that one tiny color issue as i said before, Awesome!
