This is gorgeous! The colours and light effects are lovely, especially the very warm doorway compared with the back room being lighter and dusty. There are so many different objects and curiosities on the shelves/ benches that give it a really magical and realistic feel! I especially like the different fairy lanterns and the jingles above the door!
I think the only thing I don't like is the red on the door, but that's more of just a personal thing than it actually not looking good. Overall everything is really nicely drawn and it would probably work great as part of a series of these kinds of environments!
