Hi, thx for any future reply. It was a long journey, firstly I was considered that you can draw like 30-40 small boxes at page and this task will be super easy, but then I read recommendation about 5 or maximum 6 boxes for one page... Still after time I began to draw 2 or even 3 pages with 6 boxes each, cause draw only 6 boxes per day for me was pretty much boring. So I made this starting from 25th of march to 7th of may. The absolutely longest part was drawing the extensions, yeah this was helpful for future understanding how to make new boxes, but draw them without any good music seems to me like torture. Anyway thx again for reading this, I'll gladly wait for your critism and future advice. !!
