1. I think I did that while using Quickposes. I only drew the general forms. Unless you meant something else?
2. I'll admit something: I sometimes (too often) skip the guidelines. Summers50 noticed my drawings looked off for that aspect. I even have the bad tendency to draw the face and complete it without even looking at the body. Then I make the arms and every other element one by one. When I do use guidelines, I use cylinders and spheres, mostly. If it's useful, should I post sketches of drawings without erasing them?

Ah, actually I feel like I color better than how I draw. My avatar was also done by me, and I can honestly say I find it sort of cute. Buuut if I just stay in my confort zone (front face pictures) I'll never improve so I think I better color later, until I have a better level at anatomy.
