Just looked at this in gopro vr player. Looks really nice. I actually like the non-leaved trees here and the overall simplicity of the environment.
To get a more misty spooky feel I can imagine to change the sky to something more like Rumburak has done in his most recent game background
he posted the other day. That is, if you`re after something like that.
I am looking forward to the textured version.
Cheers, Klaus
