Hopefully my latest project will continue to completion.

Seems pretty good to me. But the leaves look kind of flat. Maybe you should put another layer (but more sparse, just with some leaves) that way it looks more 3D.

Masahiro Sakurai has said that art is not about what the asset is but how the light hits it. Think about that with the textures.

break that symmetry up a bit. It doesn't look natural at all.

I was thinking more about where the branches emerge from the trunk, but this is a signioficant improvement too and would likely have been my next point of critique.

Another thing is, while I have a hard time identifying scale without a comparison point in the scene it feels like the trunk and main branches are perhaps too thick considering how short the tree seems to be.

I decided to make a different tree, but I think the polygon is too many.
I think maybe the leaves are too weak for this tree.

    newmodels but I think the polygon is too many.

    Entirely subjective. Depends on what you target.

      Here is another tree with less than 600 tri.
