Running ahead and going of script really bit me in the butt this time – my first attempt was the small tree with many branches. I actually do know what a mimosa looks like, but sculpting out all the branches was much harder than expected. I suspect a better way to do this would be with an intermediate level – making several large branches with the limbs and then adding those to the trunk (not sure if this is good for poly counts though). I almost gave up here, and needed to break to think about where it went wrong.
Then I just made a fantasy tree with a pine trunk, maple bark, and oversized mimosa leaves.
And then tried putting them in a scene.
