Cracking shot but her cut off arm and part foot plust the whiteness of the brolly distract slightly. The lighting on her face is perfect.

I think I understand where you wanted to go with this. An excellent idea with the stockinged theme against the black background and a white brolly for contrast,. I think a more diagonal approach would be better to bring a bit more energy in the picture. Did you try tilting the camera? If this is a crop, can you rotate the pic so that feet in RHbottom and Head in LHtop??? Not the other way around, because the umbrella should then be on the other shoulder so not to become too overpowering in the pic. Hope that helps.

Thanks guys, I'll retake the shot over the next couple of days and use some of the tips.
