So for the first level, the road leading into the building doesn't really make any sense so I would get rid of that and mabie replace it with a sidewalk or path. The front of the building looks nice but the back is kind of a mess, mabie dont do so many juts out of the back, a bit more flat.
The second level the cliffs are too flat. Make sure you add a bit of natural spice to the cliffs, the grass also needs some add on's like tree's, mushrooms, etc. and mabie a path showing the house is used. Honestly I dont like how you have structured the house where its forwards back forwards back, It looks unordinary to me.

Good job so far on your first levels try to have some creativity in them though!
