There is alot of tile errors on the level, start with fixing that up.
The placement of the ground detail such as bushes stones and mushrooms seems very random and not very thought through.
The dirt detailin is horrible imo.
You are alot better than many who posts levels on here and as i've seen on tryouts over the years but you still got a long way to go.
Get rid of the errors find some "how to make cliffs" tutorial
I do kinda like the houses.

Its a start, just need a bit more practice
