I used the actual apple set up along with the thumbnail to do this drawing today. It's ok, not great. The edges, half tones and shadows are all poor. I like the wrinkles in the napkin...I spent a lot of time on those and should have stayed with that part of the sketch.
I used some new paper, supposedly better than the cheaper paper I've been using. But it was hard to make the change. I've been using the slicker white paper and grown used to it. That, and the heat of 90 degrees made the day a little difficult! Double click on the image to see a larger version.
