Forest Environment Thumbnails

Quick forest environment thumbnails. Getting kind of disheartened with how much I'm struggling to draw environments. Don't know how I'm going to do a project on environments in VR if I cant draw environments in 2D.

I think the forest environments look kind of generic and there's nothing really interesting or unique about them. If I want to come up with a world for my characters to live in I think I need to look into world building and how to do that effectively before I start drawing.
