Not sure where this goes, if it even goes here, but given how resourceful you all are, and …
I’m wondering about recommendations for immersive ‘camps’ or ‘retreats’ or ‘schools’ to approach drawing/seeing/being in the moment. Something at a fairly ‘beginner at drawing’ level.
Edwards’ Drawing on the Right Side of the Brain is already on the table, looking for something more experiential / mentored / not really sure.

I like Bert Dobson’s book Keys to Drawing. He talks about inner dialog while drawing which is very helpful.

I find life drawing really helps. You brain is so attuned to what a human looks like, that it will be obvious where you have gone wrong in your drawing. For practicing to draw what I see, I draw in pencil and sight sized.

I’m sitting on the bus having just finished a life drawing class. You don’t need more than a couple of hours to wipe you out, it’s exhausting. I’d recommend going somewhere with the intention of drawing for a solid hour or two, and then do something else. Shorter periods of intense engagement will stop you getting too fatigued with it. I also like having lots of materials available so that if I get fed up or stuck in a rut I can change to using something totally different. Enjoy and Good Luck!
