As others have noted, it is fun to track your progress through the years to see how skills and techniques improve. As Rony noted, even though these are early examples, the memories they bring back are always fun and rewarding.
I have included one of my very first sketches I ever attempted at the EP. As noted, this sketch is of the Pleiades. This was made with one of my very first scopes, a 70mm refractor (the same one I learned to star hop with).
When I look at this sketch, I remember the extremely cold winter night after a day of rain, and me at my telescope in the mud and muck of the dinky backyard we had at the time. I was cold, my feet were wet, my telescope had a wobbly tripod and the EP's were quite atrocious.
I knew nothing about representing an EP view of sketching, not of even using a red or extremely low wattage light to draw by. I remember using a standard flashlight, having to allow my eyes to get accustomed to the dark whenever I turned the light on to draw for a few moments, and then turning it off to peer back through the EP.
This was well before I had ever heard of the CN Sketching forums. Up until this time I had only dabbled with a few (a dozen or so) sketches. But when I found this forum and saw some of the sketches by Jeremey and others, I was inspired to pick it up again and, with the early encouragement of others here, learned to improve my techniques over time.
