I think it all comes down to some basic skill, focus, dedication and supplies. As you see, I took out my pencils as well but having to deal with so small spaces makes it difficult, you hsve to sharpen your pencils every minute, therefore I used ink.
If you don't recognize the problem, there comes frustration and instead of a therapeutic effect, you get exactly the opposite.
I didn't go for the complex ones as again I only had very limited time and I knew I can't finish it, but it's coming 🤪
