The best response to my critics may be my continued success: I just received word back from the editor of Plasma Frequency Magazine regarding my latest illustration for his zine. His response to the work: "it is great."
Already got paid for it, too. Always nice to get paid for my work. It's especially nice to get paid for my art right after some miserable writer insulted my art. It makes me want to stick out my tongue and blow a big raspberry in that writer's general direction!
