Trees:
These are nicely done, although the only problem is they take up alof ot the level, this wouldn't be a problem with lots of levels, bt with one its not that nice.

House:
Nice house, Havent really seen that before which is good, maybe you could have done it slightly bigger.

Grass:
This is your weak point, try sepearte trees, ponds, bushes, rocks, rivers, grass, swamp, flowers, statues, signs, anything really to get rid of the boring look.

The main reason it looks bad is:

-Dirt Path, nothing interesting here
-Long Grass, Its just long grass and nothing else by it
-The dirt circle thing, that it awful and wrecks most levels. (dont use this too many times)

Sparks Rating: 5.5/10
-Only due to the grass detail, liven it up a bit more.
