hello friend, thank you for your positive support, about 5 years ago I started working with this technique and I liked it a lot because it demands precision and details, and it is very useful to advance in others, before I drew in chiaroscuro, oil, pastel and others but When I wanted to draw with a pen, I could not do it, it was a disaster and so it was that I looked for information and started practicing the textures and little by little I was moving forward, thank you, greetings.
