Yes, the hands are a bit large. That you might want to think about.

The neck is long, but it is a very idealized look, and I really like it. I would not shorten the neck. This is part of what makes this figure different from all the other dumpy males out there.

As to the poly count... who cares? We are 'way past the 2 Gig limit of 32 bit Operating Systems, and I'm still waiting for my Poser Pro 2012 to bog down due to high poly models. I've rendered scenes with 12 M4/V4's plus a full modeled environment, and there was never a hickup. I think it's time we stopped worrying about how things are going to work in Poser 4 and moved on to what we have to work with these days.

Go for it!
