Testing the coloring skills or the lack there of . . .

So I’ve started working on a personal project with more of noir feel. Most art I’ve seen in the noir genre is gritty and dirty which is challenging for me as my line work is pretty clean. So I’m attempting to bring that feel with colors. Here is a test image I was playing around with. Let me know what you think or any colorist out there, please feel free to offer advise!
