I'm quite fond of the portrait. You should do more abstract portraits like this one.
The second one where I'm guessing you dropped some blue food dye in water? :)I enjoy the low angle of the last photo; it's just a good composition. And I like the fifth to last one, the black and white of the water trying to flow over the rocks.I'm not sure about the fifth one though; I know you overexposed it on purpose, but I think if you messed around with it in editing and made the colors less realisitic, that intent would be more obvious.And the fourth and eighth one deserve shout-outs too. :)
