At the first glance i was impressed by the shot´s details and light. Composition wise i would have wished a bit more space in the foreground. In terms of impact more anticipation would have helped the shot as what we see here is just a threatening gesture but not the peak of the fight. However - these are minor issues (and just my 2-cents) - you managed to achieve a shot I´m sure countless people will envy you. Congrats!
