I went!

(10x14)
Well, I went, despite the cold and rain, and had to laugh when I got back to read all the comments saying "go"! I think I posted yesterday knowing if I said I might go, I would have to go, so as not to disappoint you! Your encouragement really gave me a boost--thank you.
It was a small group (due to the weather, I imagine) and we had a clothed model, Amy. Amy's not a professional model but she had a wonderful quietness or composure. I loved the way her shoulders sloped and her long neck; she made me think of Modigliani.
The way the group works is the first Thursday they do croquis, the second Thursday one long pose. (This seems to negate what I think of as the purpose of croquis--to warm up and to get to know model and what you like about him or her, but that's how they do it.)
Tonight was the long pose.
I began with this 20-minute sketch to figure out the pose. Doing it, I realized what I really liked were the dark shapes of her hair. So in the next two 20-minute-ish (the proctor forgot her clock, so we usually went over) poses, I just concentrated on the head.

I won't go into everything I think is right or wrong with these. I'm just glad I went!
I don't know if the group will be a good fit for me, but I'll do a couple of session before deciding.
And there's another group beginning, for a limited time (six or eight weeks I think), April 21, and I may try that one too.
The place of concentration life drawing takes you is addicting!
