I say no aswell, thus making 4 no's and an overall veto. I'm sorry but here's how I'd make it better;
[X] Make it larger, you shouldn't have to crawl to get into your bedroom
[X] Make flooring, simple hardwoord plain brown would work, its unappealing to look at a metallic floor.
[X] Give it a unique touch, something that makes it stand out.
[X] Add something to the exterior lawn area.
