As I have looked at your drawings I have tried to figure out what they represent, like which head is yours, or even if you are in the pciture. My conclusion: I have no idea. Which I think is an essential element in art, the "who knows?" element. That way the viewer can project themselves into the art and take their own meaning from it.

Dar is everyone of those people in her dreams... uh.. i mean cartoon. -Brian

I'd say most are observation, but of self and others, not much difference really...oh, I don't know either. And yes, the point is that people notice, discover and/or laugh at the "self" they may see.

Which heads are Brian?

Brian would need to tell you that.
