I wrote a little while ago about a drawing realization that I had. I didn't realize until tonight just how significant that was. I was doing some sketches inspired by Kiki's Delivery Service and I realized that, for me, I need to draw slower and more deliberately; to draw as if I were drawing with a pen all the time. No guidelines or starting the drawing soft/light.
I can only speak for myself, but this seems to be a major improvement in my drawing style. I'm always looking for that spark of magic that makes an illustration special and I'm starting this year off with a great vibe.
