That is such a cool idea for a meet up! My town has a studio where people can pay money to test wines and create a guided painting. Yours looks a lot more fun!
That pour over render is really neat! I love the copper detailing. It makes me wonder how copper might affect the flavor or brewing of coffee. . . I’m not a coffee drinker myself, so I wouldn’t be able to tell, but I have a copper coated water bowl for my dog to reduce bacteria growth, and she drinks twice as much water from it as she does from a stainless steel bowl. I always wondered if water (and maybe coffee) tastes better that way.
Do you regularly follow your sketches all the way to rendering for practice?
