Really like the choice of black and white for the colouring here. I think it's quite fitting of the brothas' expressions and poses.

The shading is top notch most in most of this, except for the top guy's grey arms and hands. They could use a bit of work.

Overall, I really like this! Even if the shading isn't perfect in every spot, it's always great to see this level of detail and effort put in on a piece. Keep it up!
