Nice work, good action shots, not bad for your first time. For some constructive criticism, I would say to lighten your images up a little bit and keep your contrast high. Also find a way to bleed out those colors, if your into the dark scene at least try and make the colors pop out or just the area you want the viewers eye to be drawn to, kind of like the explosion to the right of your img193. Good stuff though, keep it up!
