I'm not sure, but I think you can access all of Olly's previous posts after joining his Patreon.

Other artists offer different packages with varying levels of support and, of course, different prices. These packages range from livestreams and individual support to sending references and preliminary sketches. You'll have to check with the individual artist to what extent you can access older posts.

I prefer Olly's teaching method; I learn the most from it - and you learn to forge your own path.
