Nice piece! I really think the feel fits nicely with the urban vibe of the art piece, but I think there are a few things with the piece that just don't quite sell it to me.
First, the transitions might need some work. You jump back and forth between these parts abruptly (notably at 1:26) and it is kinda disorienting. As a listener, I don't really know what is going on sometimes in the piece. The composition of the piece is pretty nice, there are some nice chords and catchy licks, but it's important that it all fits together as one homogenous mix to be a piece. I do think you could do more with the complexity of the melodies and harmonies though, maybe consider some ornamentation and so on.
Second, the mix isn't very full. The repetitive piano licks are really all the listener has to munch on aside form drums for most of the piece. I wish you had added more kicks and stabs in there on some horns, some pads, or some guitar comping or something to really bring out more of the piece.
Lastly, the mastering is a bit lack. For something more pop-ish like this, the piano is awfully reverb-heavy and distant feeling. The balance feels too centered for the piece as a whole (maybe using mono sound sources unpanned?). You might want to consider using a piano that is closer-mic'd and adjusting the pan and spread of the instruments.
Keep compos(ed/ing)!
