5/10 for whole.
I notice you are too lazy to make some walls so you just "stapled" 1x4x5's, instead of working with bigger brick walls.
9/10 for the core.
Too lazy to add some bigger bricks to the interior walls? Are 1x4x5's that big of a deal to you because if so you're a very picky son of a bitch. Jerkface is right, it's meant for detail, not because I didn't feel like using OMGWTFBIGBRIX.
