Needs tidying
Well, if you're going to show this off as "art", you need to justify it - populate the room, put furniture in there, perhaps people and something that we could look upon as a spark of life.
I look at this piece and, because there's little else to see, I spot issues with detail - your lines aren't cleaned at the ends - some of them run over into the next area, after the intersection, where it should finish. This is a real downer for the piece, as it was boring already, but now it's boring and messy.
Sharpen up the lines, add some life and some detail, you should be able to get better with it.
