I also like to draw pictures myself. Due to various engagements, I can't draw pictures and show them to you, because it takes a lot of time. But I really like your drawing of this watch.

All the tools he used to draw this picture were appropriate and he used A4 paper, I also use a4. But I have a slightly thicker paper than this a4 paper which is very good and very strong.

Thanks again for laying out each step so beautifully. Anyone who sees your drawing can try to draw it themselves. Wishing you success in the competition, stay well.
