From my collection of HO trains. Have you ever tried to draw a train as it races around the track?
I need to do things with less detail because I'm not learning much filling in small details; however, it was fun.
I used a copperplate nib on a calligraphy pen with Noodler's ink. Interesting, but I wasn't pleased with the scratchiness of the point and the ink flow. Since I'm not very practiced with ink, I'll try it again another time.
