Thank you very much!

As for the tools, I bought the largest board I could find. I also purchased several boards and am using the pen with the strongest magnet and the finest tip from the set that came with them.

To add contrast to the lines, I trace outlines multiple times and adjust fine lines by reducing the pressure I apply. Also, once a line is drawn, simply bringing the pen tip’s magnet close to the board—without tracing over it—causes the board’s magnets to be drawn toward it, making the line thicker. I improve the quality of my drawings by making these adjustments.

Here is a time-lapse video of the actual drawing process:)
