Those are pretty nice Dridon. I usually don't like Bryce trees very much, but you did a nice job. They look a bit dark, but that can be the type of tree

The problem with creating top-down trees like that is the straight branches. 3D models aren't created for top-down rendering (stupid isn't it? :p ), so they do look a bit unreal. But we do what we can with what they give us, right? Your trees are way better than my first Bryce trees
