Very very very impressive! There is an astounding amount of detail here! I love the bright colors, and how you haven't neglected the background at all, in fact thats where most of the details are! I love the way the light shines down from the top of the image, and how the organic parts of the scene (like the moss) have a softer, more 'painted' feel. The tail of the mermaid feels a liiiitle bit unnatural, like it's popping out of her back or something, but thats the only thing I could say to improve on, and thats looking hard for something, because there's so much to be impressed by in this piece, incredible work. Keep it up, and thanks for sharing!
