Yeah I understood what you were saying. Theres nothing inherently wrong with tracing/gridding. I just got a little defensive because in the past one or two people have aggressively and rudely insisted that I traced even when I said otherwise.
I think some of the stigma attached to tracing/gridding has to do with copying others art, like you said, and also maybe with beginning artists who rely too much on these methods (Ive also been on art websites that banned tracing??), but its obvious from your art that youre way capable of working without them. Its just to save time. Amazing Daredevil piece, by the way.
