Back when I was getting started in #comics, I asked an established pro for advice. He told me he didn’t give advice or crits anymore because over the years, everything he knew about the biz & craft was either irrelevant or would make an artist less marketable.
Anyone who knows me knows I didn’t take that to heart. But I got it then and I still know what he meant. Things change so quickly in comics and illustration. Basic principles stay relevant, but it’s tough to stay on top of the specifics.
