Eyyy thought I recognised that background, so glad to see it put to good use!
Love the final piece and that you went with double thick cartoony/comic lines. I'm always a sucker (fitting because of lollipops!) for that style of linework.
If I had to choose a favourite pallette it's a tough tie between the double orange or purple and orange!...Let's go with double orange, it's just so autumnal/halloweeny :D.
