The first view is breath-taking! You did a great job on this one... But for me it's kind of confusing. First the island is so black, dat gives you a 'dark' feeling. On the other had you have the water in front that makes you feel like it should be a picture of a magical island.
For me on the left there is some kind of tree over te coast, I should have left that one out.
I'm nog sure, but it feels like you didn't make a choice between 'fancy' and 'dark', next time, maybe that is something you could consider.
There is te option with the dark clouds, but for some reason I should expect darker water (like in the back of the picture).
If you're going for 'fancy' crap a lot from the picture, focus on the colours of the sun and the smooth water, crap out the coastline for the biggest part, and if possible also most of the clouds or make them less 'dark'...
Well, sounds like a lot of critique, but you asked for it, maybe you can take some things out of it.
Overall, it is a great picture. You can be proud of it
