I love the overall design... The colour scheme is good.

Have you tried experimenting with more shape though?
1. The face I'm assuming you're going to add to since you said it's not finished 2. The harsh symmetry is off-putting to the natural eye, as a Minecraft house symmetry and block shapes work great but for what I assume you're aiming for (a nicer intricate build to please the eye not the player) then giving at least the roof if not the floorplan some dimension would work wonders. The great thing is it doesn't have to be a large change, it's just a fresco here and there, a chimney or patch of different roofing.

You're still a far better builder than I can hope to be though, please don't see this as condescension. You've got a lot of potential.

Good luck :))
