This is the CI that keeps getting denied It's literally just for thick line art but I've been using the 2px rule. Help please :) I don't want to be rejected again :(...
I don't know if you're still looking for help on this, but have you tried drawing the item at a larger size then shrinking it down? The line art does look a bit thick, but that should help. My only other advice is to try a 1px line.
