The idea is interesting (I do not recall anything like it), but the aggressive post processing is completely pointless here. It makes the image look like an over-processed game screenshot. You should first decide on composition, camera placement, etc, and then add effects.
My idea would be to try with straight vertical lines (camera correction) - although perspective distortion might also add some suspense to the image (vertigo-like feeling).
The "house" is also not symmetrical, so maybe it would make sense to extend the area of the view in the direction where the "beak" is pointing. It could add depth.
With a camera angle like this, it will be also very hard to see what is inside, so either you would need to render a few shots from different places, or... make the floor transparent? :)
