I forget which one I read up to cause I borrowed them all of a friend but there was a point where he had stopped too... there seems to be a run that is out of print or something, I'm not sure.
I reallly enjoy drawing Usagi though. It's one of the only anthro things I really dig... but then it's basically just Miyamoto Mushashi and Kurusawa era samurai movies which is pretty much all I watch so it's no surprise I guess.
God it's amazing. I think the guy used to work at Disney, not sure, but there's this one panel that sticks in my mind which is like the interior of a warehouse and it has all these metal beams and supports across the ceiling and it's PERFECT.
