Nothing definitely wrong with it, as far as I can see. The two things that may confuse the audience are a) the snow(?) on the ground, and b) the outline of the building behind the dumpster.
ad a) It's unusual that the ground is much brighter than the walls around, but that is what (fresh) snow does, given enough ambient light. Which means that the walls around are either quite high, or should get noticeably brighter lit towards their upper ends.
ad b) At first glance, the vertical lines and the edge of the snow on the ground strongly suggest that the building has a protrusion there, like an outward vertical cable or ventilation shaft. But the edge of the snow is around the dumpster(?), not the building itself, which actually has an entirely flat surface AFAICT. If so, you might want to remove the vertical line that intersects the right edge of the dumpster lid (and the change of the background color aligned with it) to remove the confusion.
I'm unclear whether the background end of that alleyway is entirely closed or not. If it is, the guy with the weapon(?) is standing literally with his back against the wall of an impasse, an unusual position to take in a fight. I'd assume that part of what the fight was about was to get to the dumpster and retrieve something from it. (Hence the open lid. And that he's still standing there because, after making his way to it through his opponent, he failed to find what he was looking for and is a bit confused right now.)
Random ramblings:
If the circle (window?) is indeed meant to be a circle, I think that the angle in which we're looking at it should make it appear a bit more elliptic (narrower) still.
The weather in that place has enough humidity to warrant putting even a back alley(?) door up atop a couple steps, but not enough rain to warrant a matching awning.
Given the stair-rails, I'd expect the door to open outwards, even if building regulations happen not to mandate so. Which means that it hasn't been opened recently (or else the snow would've been swept off the topmost step). Locked, and thus completing the dead end?
