This year, I did not only aim to finish Inktober but also to release a landscape, A5-size booklet containing all my drawings. I made 30 pieces available on Gumroad and 10 more "offline" to raise money for a Hungarian animal shelter (from which we have adopted 3 dogs with my family). The booklet sold out in a pretty short time and I donated all the money from the sales to the shelter.
These 40 booklets allowed me to buy 500kgs of dog and cat food which is inexplicably great help for them since they are literally struggling day-by-day with the sustenance of the shelter and its more than 300 residents.
All the drawings were made in Procreate, entirely on my 10.5" iPad Pro, based on this year's official prompt list:
