So I'm continuing my 'Net studies and have done up another page of some Timms.
The ones in pencils are done straight from some Timm originals and the others are just done without reference with a plain 'ol pen and marker.

These are just a couple of sketches I did just trying to incorporate the Timm style. The lower leg/feet I've found to be a problem.

As far as what's next, I'll figure out as I go; hopefully some sketches with the feet actually included in the next round...
