Very nice image. Colors are bright and gay. I think it would look better if everything in the sky would be moved more over to the right. Right now, the island is too much precisely in the middle of the image.
And there are some small disturbing white spots here and there in the sky - particularly in the upper left corner. You can easily fix that.
Oh my ! I have to write a hundred words and I only wrote 66. So let me go on with the spots : there is one to the left of the road sign which really doesn't need to be there.
