This tree was an experiment, I used purely geometry nodes.
This was my first tree I've ever made and I learned a lot doing it, it isn't really useable for anything but It was a fun creation none the less, it went through a few iterations as I tried to fix it, but it still is a rather useless, very resource hungry tree at 1.1 million polys!
I have since learned, individual leaves while pretty are entirely unusable, I was hoping the geometry nodes might have some mitigation to the polys but, alas, no. :D
