7 doesn't really mean anything, it's just to pull out the blue a bit xD Although it is a magic number?
I dunno, Piano Master's and his little rat Sunny are characters leftover from my first year on CS, during my favorite CS event to date: the Dream Event! So many memories from 2013 ('; I was such a noob then; I only saved about half my items ;-; But that's ok, bc I was seriously binging that year and had plenty of tokens to spare, despite some wasting. They're so hard to come by now!
The concept is almost an anime character, I guess. I love the butterfly costume though, and I though the yellow contrasted nicely with the blue. The green sweater's just there (I know I should've edited more, but I'm lazy; if I do it later, I'll resubmit). Hope y'all like it!
