Were can i find Zens furry art?

Zen's art can be located at multiple websites.

Professionally set up, (not just threads) I believe his work can be found at Furaffinity.net.

To get to his gallery, type furaffinity.net/gallery/zen.

I believe it will take you there, I've yet to check.

His work can be found on thread sites, or sites where people upload art they've found to a categorized link.

Some sites you can check around in...

vclart.net

fchan.us

paws.ru

I hope I've helped!

:D
