Wow, this is very pretty. I think your style fits with the character well because I've always thought Ariel was very pretty as well, and gracious. The way you drew her, her face especially, really does her justice. And the coloring is gorgeous, I particularly like the little corner of flowers (or coral) down right.
very cool. i love the detail, the proportions are accurate and her facial features are great. i also love the way her hair is flowing, reminding the viewer she's underwater. the bubbles are highly detailed too. all around great job
