That means a ton to me, I'm really glad this helped someone. Thank YOU! :D Punchlines don't matter quite as much in a comic if you accompany it with entertaining artwork. For example, "Garfield" comics suffer horribly when they have a bad punchline because of all the boring copy/paste artwork. Meanwhile, "Monroe" comics handle the bad blows better because they're appealing to look at.
Great advice! Sometimes it's hard to figure out how to fit a complex or combination of emotions into a face at once, but the idea of considering it just one step at a time (an element of this, an element of that) looks good. "Keep what works, leave out the rest"
