It may be a good snapshot of an interesting event,but nothing more,I'm afraid.You said in your comment,Gil,that you used to march with them; then it would be easy for you to get closer to the band and shoot their fury and excitement from within,not as a tourist who passes by.Happenings like this have a great photographic potential,and it's a pity to treat them with the 'point-and-shoot'technique. Your photo is also slightly tilted to the left,and I think the composition should include more of the band and less of the people.Regards,Kostas
