The texture on the leaves is great, but I think the trunk looks out of place in comparison. More detail and greatly less dithering would look better, imo. I agree with the tree looking out of balance, but trees lean irl, too. Maybe add another branch that comes forward.

Very nice texture of the foliage.  I could be wrong but maybe add an even darker 10th color for more contrast on the trunk for shadows and texture.

 Like onek said, it seems out of balance. The leaves look like your looking at them from a direct side view, but the trunk is at an angle.

The leaves look really good, but the trunk looks plain and boring in comparison.

Also, if you were going to use this for a game, you'd either have to make several variants, or make your tree a bit more generic, otherwise it would look a bit strange with a bunch of them in one spot.

overall very nice the leaves and the texture of the wood are done rly well , but somehow the tree seems out of balance to me, like the leaves should be more left... also the  perspective is kinda odd.... the trunk seems to be see from above while the crown is in frontal view... donno somehow feels like it... anyway good job.. nice colors with those classic blueish shadows
