Beautiful. I often like a full and vibrant background, but here, I think that would only distract from the beauty of the merpeople. Their affection is captured perfectly, and their shining tails are quite the eye-catcher!
It's sort of "soap opera" romance at best. Funny thing is I'm just following the outline I was given. Bring a tissue box with you. It's getting dramatic -organ starts playing every soap theme he can remember-
read the first chapter, im going to start with part 2 lol since you dident do the first part, surprisingly im not at all lost, it reminds me of a story i made up only the guy was human and the girl was the mermaid xD
