Well, mostly just playing around with some tree textures, and ended up making this
I know the textures could’ve been done better, but I lack the knowledge. Anyhoo, C&C please!
The tree textures have a vague similarity to mossy concrete.
Try using a voronoi texture for the bark and stretch it vertically and use it as a bump.
Also, try fusing the faces into the bark, it’ll look more convincing they’re part of the tree.
