Hello @achristopherart! I admire you for having the patience to do such a small and detailed drawing. I've never done a so small drawing like that, not use magnifying glass for drawing.
However, I love the result, especially looking and the close-up photos. It's fantastic. I can see where the 25+ hours were spent.
May I ask what kind of pen were you using? Must have been something thin.
Anyway, congratulation, exceptional work!
Hey thanks. I use a Rotring Isograph pen. Size .10. They are refillable and pretty amazing once you get the hang of them.
Thank you for getting back to me. I have to look for one and try it out.
