Comparator Mirror drawing (Basic setup from Tim's Vermeer)

My very first attempt at using Tim Jenison's comparator mirror setup. Took about 15 minutes to understand how to properly angle the mirror and align the reference to the paper sheet, and another 20 minutes to get used to the technique. I used a regular mirror that i had lying around, a surface mirror would be the proper tool to use. Music: Gymnopede No1 (recording by Kevin MacLeod)
