I LOVE pin ups like these! The whole Varga Girls theme etc is something I want to try one day (soon I hope, pending suitable models and access to studio & equipment etc).
Photos 2, 4 and 5 are my favourite out of these. I do agree with others opinions that there are some shots that are cropped a little tight. The lighting in these aren't doing it for me really but you are on the right track with the style of shots, poses, model etc. Wondering if perhaps a different colored background, like a bright white or a black background, would work better for your theme here? The greyish toned background dulls things down, in my opinion anyway. The cheerful and flamboyant style of a pin-up/varga girl needs more oomph.
I really like your other series with this same woman. What a great model by the way! Does she do this as a profession, normally?
