I am pleased to say i am back to disagreeing with you. You have to use imagination to fill in the gaps. I thought it an effective photo as a sophisticated teaser for gents with subtle tastes. Also, some woman would no doubt prefer classy rather than sexy photo be publicly posted. Also, more skillful overall than the recent face only shot posted on former QQ thread (of Sherry I believe).
PS: How about something similar with Eva, showing her in say a traditional chinese dress with a long slit to expose her pretty legs. Face could be hid to protect her privacy. Would combine traditional culture and sexiness, and attract refined and higher-income gents - a good target market for her style & personality.
