The blue was really more of a highlight color, since I had a lot of those blue hands from the last wave of HF sets and wanted an excuse to use them.. Even when I did the little Inika Isthra for that Xoth picture, I had trouble incorporating it satisfactorily. Some light blue/teal highlights would be fine if you so choose, or it would work without the teal at all.
As for the leg design, well, it works. The feet look a little flat from the front, though looking back at Ahsanka, they look fine form the side view, so no real complaint there. Can't wait to see where it goes.
