Thanks for all the great responses! I can now obviously see the chin needs work and the eyes are way too far apart and not "round" enough. Those are two quick fixes that'll help a tremendous lot, I believe! Thanks for the pic Fyrene, but I've already got it!

As far as programs go, I've just been tweaking the P4male model with Poser using magnets. All the morphs being applied have been made from scratch. Thanks again!
