Several canid heads =)
When I went to college today, I took a book on canids (one with lots of pictures ;) ) and had fun doing this during class :D
An hour and a half, I think o.o
Reminds me to be happy to the fact that I can pay attention to class and at the same time, draw. The teacher asked me something during class thinking I was concentrated...fooled him >3

And I know these ain't perfect, I doubt it's possible to know the race of all these 6 o_o;
