Back in the groove

One of the reasons I've been extremely inactive: I've slipped out of the drawing groove. Lost the rhythm and flow of it. Today, though, I've got it back.

I'd like to post just the lines for this, because I am so fucking proud of them, but I know exactly what would happen with them. So now you're stuck with the beginnings of my shading. Literally about a minute into it.

Of course, this is not for use.

The gas masks are referenced from real-life canine gas masks. Just google dog gas masks and you'll probably find my reference. Modified slightly, of course, but basically the same.
