Is this a bad drawing? It's not great, but I enjoyed doing it and like some things about it, but it's not great. This drawing was actually my second attempt, my first effort was the next drawing to the lower left; a quick ballpoint pen sketch that followed the original image more closely. Notice that I removed the fence in the second attempt to simplify the composition. This tiny building with the ridiculously large vent reminds me of a robot head and I decided to play with that vision, so did a few more quick sketches. I also did multiple drawings of this subject because I wasn't satisfied with any of these drawings. I felt like they were "bad" because I didn't capture the soul and character of the building as I remember it and what I see in the photo. Even so, I am satisfied with myself for pushing through and continuing to play with this subject, that was fun, so it is all good. The moral of the story is, keep pushing.
Now go do your own bad drawing!
