A little loose sketching before bed

I was itching to do some sketching before I went to sleep tonight and all I had on my nightstand was this index card notebook and a ball point pen. I used to never draw with a pen, but I'm now seeing that it's forcing me to loosen up and commit to my marks...and build on them rather than trying to make them perfect the first time. Give it a try...you might surprise yourself the way I did. :)
