I'm a little confused here. I notice that you've classified this as computer landscape, yet have described this as trees at the Roman etc. ?
I'm looking at this as a manipulatipon of an actual photograph and as such I think it is great! I love the translucent feel to the trees and the roots are significant and a great part of the picture. The framing (or composition) is, to me, perfect for the subject.
I would be very interested to get more feedback from you on this photograph.

A very interesting effect, and beautiful too! It's one of those images that you have to view at full size to appreciate and then it really is quite beautiful...

great effect, it makes the trees look alive and creepy. well done

Very neat effect. I like how the trees are glowing. Well done.

These trees look enchanted Ray :) Those long gnarled roots are wonderful spilling down the hill. The glow makes the trees lovely, and the B&W works well with the effects used. Thanks for this unique work and hope you'll do more of this type :^*>

Very dynamic!!!
