Overall, I think you should release such a map in a forum which doesn't already have a high mapper level. Here, it's a bit misplaced, I think.
And besides, I've seen some other tiny maps, with similar concept, and I dislike them (except if it's meant to match who's better, of course.)
And if you keep it as it is, well, I don't say nothing to that. Mappers got their own ideas, concepts, gimmicks and so on.
If you want to improve it, I would like to share idea to you. I did drawing of it, so you would understand my idea. (professional paint use

)
And room gots all sorts of boxes and so on, so it would be more interesting to play and build. If you do that, you might create interesting map, atleast with its desing.
Best luck with your mapping adventures.
