Hi guys, this is a picture i'm working on for a super secret project

it's one of my first ever pieces of pixel art (excluding doodles), and I need some help getting it past a sticking point. You guys seem to know what your talking about, so I thought i'd open it up to c&c's.
It's clearly WIP, and theres plenty left to do, mostly details like drainpipes, drains, grass texture, door handles, plants, interior through the windows, the roof, etc etc. I'm going for a crisp 'eboy' vibe, so I don't want to muddle it too much with texture and stuff, but something about it is buggin me, it doesn't "pop" yet, I don't know whether it's the colors or what.
Any advice for a pixel n00b?
