@rcleary171,
Welcome to a2k, rcleary..
I'll suggest you read the new yorker guy, robert mankoff - before he gained admission himself, he sent cartoons for along time with apparently a zillion no's.. He has a new yorker blog.
You probably already have read him and I don't mean to be teacherly.
I like your cartoon - (don't get me started)
This may be an opportunity for some of us to get into a thread re our own stuff.
