I am sure your pictures are very nice but i don't think its reolistic for anyone not to show the face as it could be just about anyone.
As for real professional or just any friend taking them - has to be a professional one as the lighting is needed to stop what we call in the trade 'noise' - Anna would know what that means and any professional photographer.
Yes your pictures are nice but no face and i do reolise that guys aren't looking at your face but i have to say that those showing their faces get more results in my opinion cos they will move onto someone that does - i know this cos i'm told this by my guys.
Anyway its just my thoughts sure you are a babe - but who knows?
