This drawing took about an hour to do, I also got the idea from the roselia Symphony gear event (I think that was what it was called). I'm starting to draw the digital version as well, but it's gonna take a while.
I was just doodling around and somehow ended up doodling some of my fav characters from the idol/band rhythm games I play. It started with Syo and Kaoru but then I jist doodled my top 3 from each game. I didn't use a reference for Kaoru, Syo or Ai but I used a ref for the rest as I haven't drawn them before.
