Lounging Cat Sketch

Lately tv time has been sketching time. Finished this one tonight during Smallville. I have never drawn a cat of this girth or in this position before and it was trickier than I expected. I had an especially hard time with the depth. To really get it right I would have had to pay better attention to the subtle value differences in the reference photo. Maybe I will revisit this one soon, and not when I'm watching television ;P
