I like it, you can clearly see the tension in his face, and the moody underexposure + spot lights in the BG really emphasise the before-fight build up. I like the low viewpoint you chose, with the glove being prominent in the FG, it really gives a sense of being in the ring. Excellent work sawdust
As a variation, I would've liked to see a bit of the crowd in the BG, just to add to the sense of anticipation + excitement of the impending fight
