Tough Guy

Decided to do a doodle before I go to bed.  

Just wanted to draw a tough guy face really.
Used Ron Perlman and Lou Ferrigno as reference.

After drawing it I kind of wanted to draw variations because I'm positive I could come up with a cooler looking mug if I just pushed things a bit more.

But I'm sleepy and I really shouldn't be spending a lot of time on this stuff in the first place haha.

I'll save that for another day.
