I noticed you took quite a few shots from outside the arena which means there is bound to be a twig or branch blocking your way. The net can also be a nightmare when it comes to focusing.

The marshall didn't allow you to step into the arena?

Ahh, I used a DSLR as well when I was taking photos for a paintball tournament. I am not an expert by all means but it is usually better to go with the mask and enter the arena. Was using rental masks as well but they could have given me a better one, not too sure.

It takes a while to get used to looking at the viewfinder through the mask but I am sure you will nail it in future events. Good try and keep up the good work.

Ask Aaron to let you tag along with his weekly sessions then you can take more photos as well. Its quite an experience to be in the field while they are shooting each other. No pain no gain so when you are inside, you get better angles as well.

Just be alert to make sure no one shoots at you and be prepared to shield your camera with your body at times. Wah seh, I speak like I got tons of experience but only shot one paintball event
