Wow, this is excellent. Her body and shading is perfect. I see no reason for censure myself unless I don't know what the Gates of Isiris actually means. You are missing a horizonal line but since the picture has a slight dreamy feel to it, I don't think it's necessary. The wall is also drawn very good with the little details making it more real. Excellent job!
I like how yours turned out. The Egyptan theme is very nice.
