Doesn't look that great. Colors don't match well with the theme (nighttime = cool, yellow/red = warm) and the amount of different colors make it clash too much. The print brick speakers dont look good either.
The bar needs a lot of work, it retains very little of the glow bricks theme. For instance, the tables and stools need more glow, and a less generic design.
Something that I was once working on can help clarify exactly what I am talking about.

Glow is also prominent everywhere, and the lights and effects arent bunched up into a small space. Speakers are not visible; however, they don't have to be due to the nature of how they can be place in real life. The latticework and central DJ also isn't a generic structure; rather something that would not work for anything else other than a nighttime outdoor DJ setup.
If you allow rating, i'd say 3/10 right now. It does look like you put in effort, but it needs a lot of work.
Not trying to discourage you. Keep building ;)
