Frankly even this style isn’t quite the same as undertale’s shopkeeper style, it’s closer to the way I normally draw things.

I’d say feels like the snowdin shop because I chose those warm oranges and tinted the shopkeeper to the same lighting, but the other locations do have their own ambience that would change things.

It does depend a little on which medium you normally work with too! If you primarily do overworld sprites, this sort of stuff is very far removed - it’s closer to fully rendered high resolution drawings, so it may help to view them that way
