This is really good ! I always found that there was a lack of sets whose theme was centered around music and sounds in general. It's refreshing to see that someone thought of it. It really deserves to be integrated in the game.
Thanks a bunch! this is so sweet of you, i thought i'd do something as upbeat as the game style hehe, i also really like your Valkyrie set, it's so cool i can see in ingame already, dig your painting style too <3<3<3
