I feel those butterflies when I finish something big or something I'm particularly proud of. Sometimes, it's as small as drawing a picture I end up liking a lot more than I thought I would, and sometimes it's a bit bigger than that.
I definitely get the butterflies when I hold something I've made in my hands, finished and printed. When I first held volume 1 of Grassblades in my hands, I actually got a bit overwhelmed. 100 pages of comics and extra content weigh a whole lot more than I thought it would!
Also, whenever a reader reaches out to tell me how my work makes them feel. I love those little messages on my wall. <3
