Wow! The colors you used are amazing! I love the silvery scales of the school of fish, as it really makes it feel as if we're underwater with Ariel. And she has such a sweet smile - a lovely touch to a beautiful artwork.
Finally found the artist of this masterpiece! I love every single bit of this drawing and I want to thank you for sharing this. I do wonder what kind of brushes you used despite that the program and tools don´t matter much, but more the knowledge behind it.
