Oh you're right I'm very sorry, I managed to totally forgot about it these last days… I was so busy and tired ! Anyway I'll do it asap, maybe tonight. This week for sure.

I feel like the lower parts of the leaves lacks of clarity. It's very hard to see them, and they don't seem to follow the same pattern than the upper leaves, they're too noisy. Otherwise, it looks pretty good, but you shouldn't forget that the leaves part of a tree is usually really bigger than the trunk. It's a very common error when people design trees, I know it's often made on purpose for gameplay concerns, but I think like there should be a way to make them more interesting. All games features tiny trees, as if they had bushes proportions. Why not make more interesting ones.

Just look at google. Just the few first results :



Take a look at your proportions :



If I take the thinnest trunk and put it under the biggest foliage, it looks more realistic :
Also notice that the foliage casts a shadow on the trunk. Lighting is extremely important.

There is no "better". They are not real variations, juste subtle saturation & contrast adjustments, so it's all about your needs in your game. What feeling this place needs to convey ? Is it a safe place near the beginning of the game, or is it a decaying forest near the evil castle ? This is the kind of question you need to ask yourself.
