Hey, this is gonna be a crazy ride, so hold on! Well I personally like this picture, but like a lot of work, it also needs work. The main thing that is getting at me is the view, I would like to see more, maybe a 16:9 kind of field, much more widescreen, as I feel some of the foreground rocks are distracting the viewer from the awe-inspiring skyline. Looking at your meta data, it was a 80/1 of a second, would you maybe con side taking this image but with a longer shutter speed? As I feel this would give the water a milky effect, and hell, everyone loves milky water.
The way the light saturates the water is a great use of colour, the recurring colours mainly consist of clearly, orange, blue and purple gives it a late summer theme. Also, off subject but that mountain looks like a volcano, aha. You've made good use of the vertical rule of thirds line - the end of the foreground, and the beginning of the shoreline, giving the viewer a easier image to look at.
for my ratings, I gave them what I think they deserve, I'll go through them so you know what you got, and why;
Vision : As I see a recurring theme with the colours here, i gave you three and a half stars - If there was some more signifiers then it would of been a higher rating.
Originality : I've seen other pictures like this, but none with the colours you used, some of the ones I see, have have critiqued have a heavy amount of photoshopping in to enhance that. Here it looks like you've only edited subtle themes.
Technique : Again, three and a half, only due to the shutter speed and the crop factor, I feel if it was maybe a little more to look at, this would of easily been a 5* rating.
Impact : A clear four stars, this pictures gives Sicilia a feel of mystery. I'd love to go there one day.
Overall, it's a really good picture, I really like it - but like a lot of things, it needs a little work, not in the taking bit, but the crop factor part.
Well thanks for reading, I hope you take this forward in your work. - Keir Brennan
