Good capture, I like the expression in the face of jockie number 4, it looks like he knows what is going to happen next and there is nothing he can do to avoid it. Shot would have been stronger if you had some facaial expression from the falling jockie, but that is only my opinion.
I am also in Kildare town, and like you have been wondering about clubs in our area for some time now.
I wonder if any of you had a chance to check out the Dunamaise since this thread was started. Have you any feedback on the club.
I am pretty new to photography and would love the chance of learing some new skills in a club like this, as i dont get out enough with the camera at the moment.
