Yeah, I thought this was a very interesting and insightful article/blog post.
I think the figure painting community is generally very friendly and supportive to new painters. We're encouraging and that is fantastic. But I also see that it sometimes leads to frustration from people when they're still getting 7's in the gallery and not 9's. Or when they might win a medal at a small local competition and but not win at the big shows which draws painters from all over the country or all over the world. When I read Jessica's post, I feel like it's more directed at those people. I don't think the post is mean or bitter, I just think Jessica is providing some tough love for the painting community. At least that's the impression I got.
To be honest, if you don't care about awards and gallery scores, then I think you can enjoy painting with just 1 hour of practice. That's one of the wonderful things about art. It's a creative endeavor. Doesn't matter if it's an award winning piece or not, you've made something and can take pride in it. If you put in the time (say, 10,000 hours) and work hard then you can become good at it. And, if you put in even more time (say, 75,000 hours), then maybe you can become great at it and win those top prizes at international competitions.
