Thanks for all the comments. It really shows different perspectives. I'll provide my thoughts on what I was trying to achieve for each.
1. The water around Pinnacle rock was a lighter color blue than the surrounding ocean, so I wanted to show that. It was a very very windy day so the 15 sec shutter speed helped smooth it out. I should have experiemented with a longer exposure as stated, which may have brought this out more and would have added more light to the foreground. I do however like the dark mood this whole capture provides with the darker FG and the thick clouds.
2. I wanted to go for a silhouette treeline, with the remaining sun lighting the water. I think I achieved this, however I agree that the FG rocks should have more detail. This is an image people either seem to love or hate.
3. My planned trip to Mammoth was a bit late last year as the colors were already fading. I still wanted to capture the fall colors fading, with the winter season approaching, this adding the left FG tree into the frame. I agree that it is a bit "in your face" and may be better from a perspective slightly more to the left thus not as pronounced. I also agree that the reflection is a bit tight at the bottom. I do plan on going back to Mammoth this year, hopefully in the prime of the season where I can reshoot.
4. I was going for symmetry here, however if I were to reshoot this, I would have moved the FG rock more to one side, and not split the horizon as stated. I think a bit more contract does look good too, more pop to it.
Yantropov - I have the D7000, and use the Tokina 11-16 for all my wide angle shots.
Aloicious - Did not go to Bodie, but did stop by Mono Lake about 3 hours before sunset. I was with other friends who are not into photography so we did not stay for better light. Part of the reason I like to go out shooting by myself.
Banderson - I'm also planning a Portland/Seattle trip this summer with the wife. Going to be checking out Columbia River Gorge and Mt. Rainer. Hoping for good weather!
Compaq - thanks for the detailed feedback.
