To be honest, I don't like half of them. But other half is quite ok, with #5 being really great. #1 is nice one, but it's pretty much typical stock work. #5 can't get any better, so you can get only congratulations from me for this one. And #6 is nice one too. I can't help it, but I somehow don't like other 3 photos. Surfing and long jump are not caught in right moment (at least for me), and not tight enough crop, and that portrait in #2 is nothing special... just portrait.
But as I wrote... when you see #5 nothing else matters. So good job!
