This a new piece that I'm doing in response to all the response that I got in the critique forum. Let me know how it's going.
Your caricatures looking good, the Obama more than the McCain.
But notice from a photo ref. that the lobe of Obama's ear does not connect to his jaw but flaps waaaay out.
For McCain, it is a good thing in doing caricatures to capture the personality in the eyes of the subject.
