Bill, I'm about to snap. I love drawing, but all my work has been sporadic and small.  I'm about to do a bigger project. I'm scared it's not going to turn out the way I want, and I barely know where I am going to start.  What's your advice for these situations?
doing a medium sized project may be just the ticket, but if you really want to get to that larger project, just remember the golden rule which is that the 10th will be much better than the 1st, yet the 10th will not exist without the first. and the second rule is, doing bad work can also be fun. so get to it, and enjoy
