Wow. *Nicely* done.
I was opening this going "Oh god, more completely dull and uninteresting sunrise/sunset shots", and was pleasantly surprised. Thanks for showing me it is possible to get interesting pics with this.
1st and 3rd are very nice... though something about the position of the sun in the third doesn't feel ideal to me. I think I want it more to the left.
In the first one, I feel like capturing the picnic table was bonzo, but somehow I think because it is so small and not enough the subject of the shot that it actually becomes a bit of a distraction. I think I would crop or clone it out for this shot and try to get another shot where it is more obviously the subject (along with the reflection, which is cool).
Still, both are fantastic... these are just my suggestions for how I might try to push it even more.
