Yea, looking at the forest now gives me some better ideas.
The texture was a quick try to simulate bushes or low density vegetation, i'll change that because it looks fake atm.
Ilanthar you're absolutely right, that's probably what was bothering me, I'll have multiple "levels" of light/dark shading to suggest clusters of higher/lower trees and elevation change. I'll also add some clearings/holes in the forest, make it look less like a single mass of trees. Lots of good ideas of improvement!

Thanks for the feedback
