I was looking at what Pixabay might offer as inspiration, and found this fish. Perfect for a ballpoint pen drawing. The incompleted drawing in the second photo was taken before the final "glaze" of little scribbles of turquoise pen across almost the whole surface. It was a happy accident that made for a shimmery, iridescent fishy quality.
It's been awhile. I spent last year trying to make color sketches with very cheap old colored pencils. This is the last one I will post. I got better pencils for 2022.
