I'm not sure if setting a specific time limit on the studies is such a good idea. Some people may prefer to do a longer study, and some people would just prefer to spend the extra time. We all have different IRL commitments, too, so we might not be able to keep a set schedule.
I'm not sure if everyone will have the same materials. I've got access to Bridgman's Complete Guide to Drawing from Life and a few Loomis books. I'm interested in the Vilppu manual but I haven't been able to find it. I've heard of Van der Poel but I don't have access to him, either.
Heads are heads, so if everyone mentions where they're studying from with each post, then I don't think it'll be too hard to critique even if people use different references. I was planning on studying Loomis, since I've only ever studied from Bridgman before.
I agree that keeping it greyscale is probably best for now.
So to summarize:
- No set schedule besides the new body part each week.
- Try to post something each week, but
- Greyscale only
- Study whatever material you have, but cite sources/references (nothing too fancy, just let us know so we can look it up)
- try to cover different angles, actions, etc.
Lastly, real life got in the way this weekend so I wasn't able to prepare any studies in advance, so here are some studies I did last week.
Edit: Oh, and anyone who wants to join in is welcome as far as I'm concerned.
