grass and landscape is perfect. But trees looks a bit flat, because you used light green color in both sides.

But in total - very good job. I put it in my favorites. 

I will have to agree with the trees looking weird. They seem awfully out of place compared to the rest, which is very lovely by the way.

 That's beautiful Zenobia, wonderful detail on the rocks and grass.. i have to say in my opinion that is the lovelist way to pixel grass that I have seen!

 pretty awesome, but trees look weird good work.
