Free wolf lineart

So, this is a free lineart for all of you. Hope you'll like it.

Rules
You can colour it, add whatever you want (claws, hair, tatoos...)
Use it without permission
U can upload it anywhere 
Don't remove my signature without my premission
Don't sell it for money
Don't claim it as yours

It's my first lineart, maybe also the last one. (Btw, not sure how to save transparent background. Maybe it'll be a little bit problem.)

I'll appreciate all links of created images, comments, favs and watches! ^^
