Couch jumping works as well (they were the dain of my existence)
I would put some gutters on your roofs, like on dustbowl stage 3 (in some areas you could make your roofs more interesting in general, dustbowl has some crazy stuff going on its roofs. and it makes them look really neat.) That being said, the flat roof style is nice.
Looks really nice, Berry; I love the colors. You should bring some of the green from the out of bounds areas into the gameplay area with some small plants - look at how Hydro does its foliage.
Also, more chimneys.
EDIT: Maybe some dirt overlays under the water to show it a bit better?
It looks great Aman! But perhaps a bit overscaled. If you use the control point as a reference then the entire area looks pretty large. But I love the height differences and your inside areas look interesting. Reminds me a lot of koth_king.
