I really don't know where to start regarding this. I'm blown away by just about everything. I do believe that what really caught my attention were the colors. The greens, blues, and purples work amazingly well and seem to bring a sense of both harmony and relaxation to this piece. They also stand out brilliantly with the skin tone, which just seems to make them pop even more.

But, not only are the color choices superb, the anatomy just astounds me. Everything seems to be top-notch, though I'm really no master of anatomy, and justly proportioned. The soft, curving lines seem to make her all the more delicate. As does the shading, and coloring.

I do believe that the most breathtaking part of this is the color, of course, but also her ears, at least I believe that's what they are. They look even more delicate than her, if that's possible. But the way they were colored and portrayed is... breathtaking.

The only real suggestion I would have is simply to make the scales on her tail a little bit darker. But not by much. Just the slightest of a fraction of a percent darker. All in all, I love this piece, and I'm still trying to regain my breath.

This is such a incredible illustration of the siren overall!

I really adore the way how you drew her beautiful face and her hair flowing down her body. I also like how you posed her, including her right hand where she is holding the seashells. Her anatomical proportions came out really well and I especially like the greenish scales on the bottom of her body. I really like how you did the fins on the back of her buttocks as well. You put a lot of hard work on how well you did the soft colouring and shading on this drawing.

I honestly don't see any problem with the entire drawing at all and you put a lot of hard work on how this drawing turned out! Keep up the great work!
