Sketchbook Suggestions (Patreon)

First of all, thank you guys so much for helping me reach my second goal! That's so amazing, and I can't believe that I've come this far. 

I'm excited to be putting together a sketchbook for you guys, and while I've already gotten some good suggestions, I wanted to know what it is you guys value most when getting sketchbooks from other artists, or something you would like to see!
