Pfft, nah. True, I hadn't gotten any yet, but seriously. "I hate your comic so much I threaten death upon you" Really? Are people that dissociated? Probably a child wrote that or an adult who thinks like a child. I say let them talk crap, they can't do anything about you and your work.
Don't let them get to you.
They're just words on a wall, like me atm XD
On a different note, tho, a little critique on my part would pique my interest, not to rethink everything I'm doing, cause it's done, it's posted--but that someone else cares enough to give helpful feedback, and I love that about people! I don't get much of that either (besides text size, i get it XD), so I assume I'm doing the right thing art-wise.
