To me it looks like the image was shot at head height, or not far off. Maybe a lower viewpoint including some of those rocks as foreground might have worked a little better.

One of the things that seems to happen is that when an image comes straight out of Photomatix it lacks some contrast that it needs to 'lift' the image a bit more.

I'll post a mod in a few mins to try and show you what I mean.

The way I'd normally do it (assuming you use PS)...

Ctrl + A, to select all (have 0 px feather)
Edit -> Transform -> Distort
Hold shift down while you (in this case) drag the top right corner further to the right - this will keep the top line completely horizontal, so it shouldn't impact on your horizon.

OR

1. Select a group of leaning turbines using a marquee with a feather of 5 px or so leaving a bit around around each side.
2. Right click and select 'layer via copy'.
3. Edit -> Transform -> Distort for the new layer with the leaning turbines
4. Repeat as necessary

Hope this is of some help

I reckon another night with a few clouds and ND grads would help this scene a lot. I don't mean that to sound flippant, but the empty sky and harsh whiteness from the sun doesn't seem to work all that well. Maybe a lower viewpoint to help to emphasise the lines from on the ground would work well too

I think a viewpoint closer to the sea to allow the rocks on the left to go below the top of the sea line would have worked better and helped to expand the view too. The light looks pretty good.

This is a beauty of a shot, it really is. The water has taken on a wonderful appearance and the wet green looks good against the colour from the sky too. I just can't make up my mind about how distracting the starfish is as it kind of stops you looking around the rest of the image. As small as it is is it seems to dominate the image. I don't mean to sound negative as it really is a lovely image.

Sean

I like the drama and the mood in the sky, but I reckon a little more space between the left edge of the shot and the post would work a little better to stop it looking a little cramped on that side

Cheers, Sean

Like the line heading out in to the sea.

On the Sigma 10-20 I reckon F22 is a bot small as the lens will start to go softer after around F16, might be worth shooting the same scene at F22, F16 and F11 and see if you can see a difference.
