Your comic and Patreon wouldn't be on my favorites if you weren't good. Considering you also managed to part me from my money willingly, without a crowbar, talks wonders about how I feel about that. (There are guys at DC and Marvel that can't do that)
Although I do know how Anxiety works (not to mention self doubt) and know it may not help me saying this. Just know that you have a great deal of Validation of how good you are already. So screw the contest, they wouldn't know art if it bit them on the muse.
