Having a full-on adult life doesn't leave much time for creativity. Full time work, housework, going to the gym, one session a week of life drawing--even when I have the time, energy or interest may not be there.
If I offer or agree to do projects for anyone, it'll be because the subject, or the challenge involved, interests me. If I'm not interested and willing, it's not happening.
I enjoy my weekly sessions in the live drawing workshop, but I'm not working live over the internet. Being technically a bit backwards when it comes to Net stuff, I don't do Skype or have a webcam, and I don't work fast enough to do my particular quality of work, working around amateur models. (One thing I have to say I've been totally impressed with, in the live sessions, is just how hard it is for life models to do the things they do, even for quite brief periods. Nobody wants to underestimate this!)
At this point, I've agreed to do two challenges that have interested me. The results of one will be posted after this goes up. After that, I think it's fair to say that while I won't entirely rule out doing things for others, it's going to be rare, and there has to be something in the subject or the challenge of rendering it accurately, that interests me.
As has ever been the case, babies and pets are OUT.
