Pim - Poser's just a tool really - it's up to the user to make something original with it and I think you've managed that just fine so I shouldn't worry about it too much if i were you :-)
Excelent work. Great composition, and it reminds me of either a helping hand, or someone in need of help. This really gets you thinking. Great to have something different on this site. Making something as framiliar as humans is risky in my oppinion. This seemed to turn out superb. 10/10 in my book.
