Very artistic render, my compliments! I also like the lighting. Is that PS? I did something like this with an extra blurred layer set to bleach. I agree about getting rid of the flare, and I would add a distant very vague stripe of an island to get more depth in the left top light area. I might adopt the presentation with the black bands I've noticed a couple of times, it's very sophisticated, and makes it more than 'just a render'.
