Just an FYI I frequently upload sketches and work in progress stuff on my tumblr:
http://silvermane77.tumblr.com/

and my twitter account:

https://twitter.com/silvermanewere

So if you want to see such works go there. I also accept critique of any sketch work posted so input and feedback is always welcomed on anything being worked on. Thanks! I also post other werewolf art on a pretty regular basis too.
