IMO the ripples on the inner part of the tree are too cramped / close together. Other than that, I like the style.
honestly imma just refer people asking about trees to your post, this is perfect. People always come to this thread asking for help with trees and you just made it so simple. FishBoks try to make the branches blend with the leaves better and make the shape less round and more organic.
haha give us more! It's hard to cc in a case like this. I guess add bark and leaves to it? Shade areas and consider things like moss/twigs/flowers. If you're wondering on whether the shape is fine, it is. Tree shapes can get quite wacky.
