@lego well it can't hurt to be more specific. I haven't had a lucid dream for ages. I generally get them when I am getting more sleep than needed, along with a load of normal dreams. write those dreams down they'll come in handy for writers block!
@ovium yup this is my holiday stash, so 2 weeks away with my family which I just got back from. yeah I generally rotate my studies with about 2-4 pages on each thing, but often fall back to faces and general body which are both important and difficult :P
as for benefiting yes I did, in that I was able to wring out some bad guidelines habits of mine, for faces and hands and body, although I wanted to draw about 3x that - 300 pages (which I have done before so it wasn't impossible), so I feel I didn't get the most benefit that I could have had, but hey it was a family holiday and I had fun with my family so there you go :P
doing a lot of art all in one go helps to open a lot of thought channels in your head as you can focus completely on the one thing. kinda how moving to a country is the best way to learn a language because of immersion, art immersion can have benefits that are hard to get with a normal draw-for-an-hour-a-day kind of regimes. being a holiday, it helped me to relax as well so I wasn't stressing over my art or anything else.
