Hmm, well I personally run a resource blog of my own.
I split things up into tags, so if you wanted to you could for example add a link to my anatomy tag under foundations

I have got quite a lot of tags though, so you might like to look through and choose ones to add yourself.

Some others I'd add would be my colour theory tag

perspective
http://helpfulharrie.tumblr.com/tagged/perspective
and composition
http://helpfulharrie.tumblr.com/tagged/composition
Or you could just link the blog under all encompassing, I dunno!
