I was an administrator over 10 years ago on the SRB2 Wiki. I currently live in Utah and am a student at the University of Utah pursuing a Doctor of Music Composition.
Involvement in OLDC
Certainly one of my favorite things about SRB2 was this contest. I look back now in 2018 and realize my levels may have been a bit ugly sometimes, but they played well. Usually.
Will I come back? I don't know. Probably not now. I would want to dedicate a bit of time if I do, and I need to get schooling finished.
Nonetheless, I would say that music composition principles can very much be applied to designing Sonic levels.
Connection to Furries
SRB2 was the first place I heard about the furry community, although not in a great light. I am nonetheless grateful for the knowledge of its existence, as it has been a great place for me to be. Despite the fandom's reputation, I like to keep myself clean and encourage others to do the same.
I never call myself SonicMaster anymore, other than the handle of my Telegram contact. I go by Scarbo, and my fursona (furry fandom avatar) is a black sheep.
