While other people are shitting on this condo (E; they know each other it’s a joke but this is still a legitimate reply), I’d like to give some constructive criticism instead.
The condo itself looks bland and empty. I recommend decorating it some more. Even if it’s not your main focus (mine sure as hell isn’t), the living room is the very first thing users see when the enter your condo, so you’ve got to make sure it’s nice. Not to mention it’s just wasted space.
The idea of those plastic preschool-lookin’ chairs in a concert room isn’t very solid. Consider changing the seats. Also, for your band room, I recommend changing more and decorating. Maybe have the room darker (wall color) with colored lights (neon bars work wonders!) and put some more decorations up, as it’s pretty bland.
Just, in general, work on it more. With the theatre you’ve gone for scale rather than detail, which can really go bad. Not sure what you could change, but I just don’t think it looks too fantastic. Perfectly functional, mind you.
So, overall I guess I wouldn’t give this condo a very positive rating. But it’s definitely salvageable with some retooling. Give it another shot and a bunch of time and effort. It might take a while but I’m sure you’ll get something good going eventually.
