I've been working a lot from life lately. And as amazingly helpful as that is, I think it can be dangerous if you don't sketch out of your head every now and then. Why? Well, when working from life, nature tells you what things look like, and it's your job to draw it as accurately as possible (which alone entails a lifetime of learning). With sketches like this, you're not even afforded the luxury of being told what things look like (or even what's in the frame!) It is a ruthless test of what you've ever learned about art. And that's scary. Every brushstroke can reveal weaknesses you didn't know you had...and I found a lot of them while sketching this. The good news is, my painting tells me where the holes in my knowledge are, and challenges me to go out and fix them. And that's why I'll be doing this stuff for a long time.
If you disagree with me (or even agree completely), I'd love to hear what you have to say!
Nice painting, as a younger artist I was under the notion that every artist had to have a crystal clear photographic memory to produce any work that was good with no reference. But I realised early on that straying from conventions allows you to become an individual artist with your own style. It's always a good exercise to free sketch.... try and style anything you see as a "flaw" into a quirk it may help define your artistic style !!
