Regret (Background commission)

This was a commission for osu!taiko mapper and Beatmap Nominator Nepuri, to be the background for the song Regret by ARForest.
You can check the original song here: https://www.youtube.com/watch?v=pO_axJ6blSQ and Nepuri's map here: https://osu.ppy.sh/beatmapsets/1184228

It's been a very long while since I've done any landscape illustrations, and this was both a challenge and a lot of fun to do.
