Now there's a dithering style you don't see too often. I think it fits well for the trunk. Not so much for the foliage.

Anyways, nicely done.

I like your dithering style! It has a cool esthetic to it.

I will try to fix the pillowshading tomorrow. 

The dithering looks nice, but the pillowshading does not.

 This would look cool in some sort of abstract landscape.

i think that looks creepy O_o

I wonder what a game would look like with everything pillow shaded. Would it as a whole be forgivable, since at least it was consistent? Probably not. Let's not find out either.

Nice pillow shading
