Hello, That's a really cool Painting! First I would address the nose: It is way too long even with stylisation this lead to a small mouth because no room is left and too much chin under the eyes. The nose should not take more than a third of the face from bottom of the hair to chin. I expanded the mouth (each corner of the mouth should go under the middle of each eyes). Then the chin was too long, I reduced it. Then to add more depth and interest to the scene I would work on the lighting. Choose an angle that put the light on the key pieces (arm, gun, face). I also had fun by chosing a striped window to add to the "hidden/gangster" storytelling of Jinx. I hope it helps you go a step further. And once again, awesome scene !!!
