Hahaha aghh, I absolutely love this style, it's so chunky and vibrant and cute! I actually studied Japanese language for a time and did get to experience staying there for a short while, and I have always loved the unique aesthetic appeal of their cartooning style. This is really charming, lovely work.
Oh that? I was gonna put StarBucks in Japanese on there but it was to long to put on the cup, so I just put the first letter on there, the real name of the shop is called Cocoa Delight on the red banners, but the title gets cut off
