As someone who started getting serious about photography about 4 years ago these are my opinions on your work.
Piece 1:
This is an excellent picture! When looking at it I feel that the emotions tied to this the most would be be serenity and warmth. It really looks like you captured a high level of potential beauty that you saw with your creative eye. Color saturation is vivid but not over the top, shutter speed was wonderfully slow to blur the water and add a great subtle softness to the reflection. I cannot find anything negative to say about this other than possibly trying to clone out the thing floating in the bottom right. I can't tell if I would like it more if it was missing, or feel that the sea is too bland without seeing it both ways.
Piece 2:
This is another stunning piece. I have yet to come close to capturing the texture of water this well. In terms of making waves in water look good, you have brought out a lot of beauty from the scene. I don't find this piece to be as emotional simply because even though I appreciate the beauty of the well done photograph in terms of shutter speed, exposure, sharpness, and saturation, I can't help but still just see it as only water, even if that seems a bit close-minded. It does appear some sort of swimming animal might have just gone below the surface, but if it is the case, the photo looks like it might have been bad timing, really hard to say with the way the water behaves in center of the frame, but I do appreciate the thought provoking nature of it, for what interest it does provide.
Piece 3:
This piece gives me a similar feeling as the first, however the photographer in me instantly can't ignore the crooked horizon. It is very difficult for a horizon tilt to look like it is executed to enhance the photo, and in almost every other case, it looks like a mistake as it is usually not desired. However to repeat this might seem a bit redundant but you definitely are aware of what settings to use for capturing a good exposure, vivid color, and sharp focus. Your use of a stopped down aperture and slow shutter speed are all spot on for a great image of these low-light landscapes. This piece has a really good balance with the black ground at the bottom. Even though the detail is low, it really does provide some sort of contrast to the bright scene. Your creative eye is well trained as is your technical knowledge. I'd advise working on a few post processing techniques to correct the smaller flaws, such as the horizon tilt, or cloning a distracting thing in the sky or water etc. This is a wonderful piece though, and exceeds my personal abilities for creativity with landscapes.
All the work is very moving and inspiring. Keep up the good work, never stop improving!
