pencil sketch?

Years ago I decided to switch to only drawing in ink to force myself to have to commit to every stroke. It was good because it meant that if I started to overwork a drawing I would have to start over again completely from scratch... which usually resulted in a fresher sketch and it forced me to learn from my mistakes. This weekend I found myself with a pencil in hand for the first time in years and started scribbling away. The experience was both very strange and very natural at the same time. I still prefer ink because Pencil is too fragile... its heartbreaking to see a beautiful sketch get smeared away into a vague blob.
