With a word of caution, as this site contains images of **nudity** you have been warned, for the human or homnid modelers, here is a link to a site with a huge amount of resources:
Figure Drawing and Portraits

The site has a lot of links to anatomy study, esp human figures, hands, heads, torsos, poses, books, even a few 3D modeling references. While a lot is geared to 2D art, some caters to 3D or total figure.

Quite a few of the links are broken, though some can be found by chopping down the url, but there is enough there still to keep one focused for quite a while.

My only complaint about the site is there are few references to modeling clothing/costumes.

Hope this reference may help someone.

Nice site. Wish I could draw like that.

Re modelling clothes etc. I found visiting some of the fancy dress sites a big help.
Most of the costumes are shown worn by humans, so you get a good idea on how clothes hang on the body.

Thats how I made my Grim Reaper model, but animating the cloak was a bit of a problem.

Thanks for the link - and the warning - I will check it out after the kids are in bed

here's another good resourse, has a lot of textures, photo images, tutorials, some free 3D downloads of you need a quick object or character

the 3D part of the site is geared mostly toward 3ds max and lightwave, some dfx. 2D, I've used their solar system textures to build a quick planet on a couple of occasions. Lot of good free stuff there.

Figure Drawing and Portraits is an excellent site! thanks very much for the reference!

Thanks also for the 3dcafe ref, however, now it needs to be found by searching from here http://www.3dcafe.com/ (they have rearranged their site) ^_^
