“Going Somewhere” – a railroad track without a certain beginning or end.
Admittedly, this took a bit more than 15 minutes but mostly because of the sketching. I kept redrawing the track until I was happier with the proportions. I was also working on fading the picture into the background at the beginning and end of the track, which was more difficult than I expected. And this was actually the first quick watercolor I did after years out of practice.
