Thanks for the comment. Any criticism is welcomed.
Yes, I do have an issue with the backgrounds as well. I have played around a lot with the colors, and it is somewhat hard to figure out what changes would not ruin the scene. Regardless, one of the reasons why I ended up using real life backgrounds is that many notable visual novels which started on a low budget did as well, such as Higurashi and Tsukihime, and even though they don't blend with the characters that much, the variety of real life images one can use helps set the mood better and more accurately than drawing and reusing the same anime background assets for multiple locations. Where can I search for several anime backgrounds of an early 20th century hospital? There aren't much options unless I'm willing to break the bank now. And using real life background images can help illustrators gain an accurate idea of the scene if I am to use anime backgrounds in the future. Anyway, that was my thought process.
