Thanks C:
I didn't detail it too much mostly because I hate to make leafs. 
 

@Felch The shape indeed may be a little strange... I'll work more on it. 
 

well you could try to flip the tree to fool our eyes tho xD

overall I like how you stylize your tree... away from details and into style more

Is it one tree? As it currently looks like (especially in the context of the mockup) one tree behind another. If it is one tree, perhaps more shadown on the lower part may help to make it look more upright.

I do like the way it has been pixeled though.
