I agree with quixote, at first I thought they were both wearing thigh high boots. That first tree on the right seems to have a shine to it. I don't know if it's the texture or actual shine but real trees don't reflect that much light so it detracts from the realism. The texture of the tree at left is spot on! Hummm...the other trees might benefit from that same texture at different frequencies, orientations, color manipulation and sizes, what do you think? I also think there is too much radiosity green lighting giving it a yellow/green cast, perhaps it should be a little more subdued and maybe also some other colors like blues added (lights) to help balance the color contrast. The image itself is quite appealing. Seems to have a nice airy and fresh feel to it, like newfound love. I like your idea of adding substance to your readings by extracting a visual from it. Very nice indeed, thank you!
