I was warming up a few days ago and they ended up turning into more art of Luke from Shelter. It was decent human practice too, so that's a bonus, especially since I drew these rather quickly :3

It was also neat seeing what more I could do with a single brush after tinkering with its settings a bit. The default dry ink brush in CSP is already my favourite, but I'll be using it even more now that I have a better idea of what it can do
