Oh, feel like I have to write pretty much this time. I'll try to shorten it down. :P

First picture!
It's very small. A bigger version would be appreciated! It is also very grainy, but that can easily be fixed by using this program. The text that says "Spirit" is bad though, it's very sharp, and white. It breaks the balance in the picture a little.
I really like the composition, it's very calm and relaxing. Colors are very nice, you can almost feel the sunrise, as the atmosphere's colors changes. The dark areas also work well. The moon (I guess it's the moon?) adds a finishing touch, which is very nice. Great job, would love to see it bigger.

Da second one!
This one me likes! But I must say that the fact that it is oblique ruins quite alot of the picture. Although I love the clouds and overall sky. This one should be bigger too! Colors could have been a bit corrected in Photoshop though. It's nothing to be ashamed of, it's the same thing as darkroom tricks. :P

Sorry, I'm in a hurry, so I will write shorter comments on the following ones.

Tttthhhiiird one!
Since the idea is to catch the carlights, the angle is pretty bad since I didn't see it until now. :P I was looking at the other bright stuff.
It's really hard to comment on this one, but I like it. Hard to explain why. Sorry for the lacking ciritism. xP

4thz0r!
This one is ok, although it looks like someone is dumping 30 tons of garbage in the water. :P Colors are nice, but there is something missing, I can't put my finger on what. :/

5thfiong! (Hell I'm funny)
It's better than the 4th, better angle, and it has more reflections in the water and more "action". I'm curious about that ray of light though. What is that? o.O
