Conceptart.org workshop any good?

You'd do better with a Schoolism subscription ($144 for a year) or Chris Oatley's magic Box course ($18/month) if you're looking for basics. I have not seen anyone talk about LevelUp for years (pretty much since they stopped spamming my inbox...), and students from these two courses have been getting consistently better. A lot of people can vouch for quality of instruction there.

Current and past students of these courses have been great about offering feedback and critique and a lot of Schoolism instructors drop in to comment on subscribers' stuff for free as well :)
