Would like some feedback on this tree:
Not bad for the first tree at all. I think you should focus on the lightning and making shadows, lets say if the sun is over the tree, why does the trunk has different lighting? Also try make more detailed leaves or something, so it doesn’t look like a big bush.
It doesn’t look like a real tree in the slightest, and I’m just talking about the trunk for now.
Go outside, look at a real tree, come back, try again.
As an artist, Google is your best friend. Look through the images and take references.
