We found this tumblr that has human poses and portraits which are good for figure drawings.
Check it out here.
Just to quote the owner of the tumblr:
Figures for Drawing
My goal for this blog is to create a place for anyone to come and quickly find solid Figure Drawing References and inspiration.
This blog equally posts male and female references and updates 4 times a day.
