I have to say, I have seen many different attempted re-rendering of mythical beasts but this is by far one of the best that I have seen. Great concept and also quite true to the basic description of a Sphynx: Lion-like body, eagle wings, and the face and breasts of a woman. The colors are splendid, giving her a natural animal feel and I like her "hair". It has the feel of a lion's mane blended with the cockatoo hairdo to make a unique and flowing human-like hairstyle. I also like the detail of the bird scales and the stripes on her legs. Very amazing work here, I believe she is flawless.

When I first looked at this piece, my impression was, "Where did you think of these awesome colors?" That impression sticks with me throughout.

The rendering (initial design through coloring) is tight and professionally done. I wish I had your technique. The nudity is tasteful. The placement in the composition is nice. Overall, this is an awesome piece except that the final presentation needs a little bit of extra "oomph."

What I mean by this is that whenever most authors create an interesting character or creature, they present this character "as is" on a white page: "Here I am." That's okay as far as presentation is concerned, but if you really want your piece to stand out, you should offer some degree of context. Show the character interacting with its environment or with other characters and give some context and background to make the character truly special. Even some sort of pattern will make the composition stand out.
