Cool pictures! The action at fencing is very fast indeed, and you captured the movement very well. At a primary school reunion last month, I found out that one of my former classmates is now an Olympic fencer for Colombia!
When I was about 17 I took fencing lessons at college and I quite enjoyed it. Somewhere I still have the little badge and certificate we all got at the end of term. And I can still do the silly back-and-forth fencing walk.
