How did you know I'm using Clip studio 👀 Jk, jk, honestly I am lucky to follow other artist that share their Clip brushes and I just grab them for trial. I'm very picky when it comes to brushes, so I tend to get back to my old favs anyway, but I'm always at least trying out what others are using.
I also tend to look through Clip Studio Assets, I usually look for ready patterns or materials there so I can save up on time while drawing tedious elements.
