I hope you like Kanto starters drinking some berry juice! (Bluk, Oran, and Cheri respectively, not for any reason except color convenience.)
I'm also keen on the idea of offering these as stickers! The catch is that since I'm a small artist without an endless resource of funds, I can only afford to make 1 Pokemon to start off with before I can think about making the other two. I do want to eventually have all three available to purchase at once, but I can't afford that right now.
So! If you'd like, vote which one you'd like a sticker of the MOST so I know which Pokemon to start off with!
