Fallen Trainers: MARNIE (Pixiv Fanbox)

Another chapter of the Fallen Trainers for you all. We're moving outside the Paldea region, and paying the region of Galar a visit, starting with one of my favorites, Marnie. Hope you guys enjoy. Also, I wanted to ask. Looking at the images after compression, I've noticed that they become sorta... Grainy. Not to a point where it's very noticeable, but it's still prevalent enough to that it can be a little off setting. So, question for you all: You guys prefer smaller file sizes, with slightly grainy images, or larger file sizes, with higher quality images?
