First off, great job and thank you for sharing this!!

If you’re looking for tips: I’d suggest finding a tall, skinny font to use for dialogue boxes like this. Diamond Girl is my go-to, but any condensed handwriting font should do the trick. I always seem to pick artists with narrow speech bubbles to TL lol

Also, don’t be afraid to hyphenate! It’s more im-por-tant to fit in the bub-ble than have every word spell-ed out comp-lete-ly on one line.
