His attire was based on his 12th single release "Shine".
...I really messed up his appearance imo, but I guess it is still within forgivable range among the fans as many of them still liked it enough to give me some positive feedbacks and critiques, e.g. "Next time have his chin sharper", or "Please make his mouth wider!". *laughs*
I hope the DA folks here will like this simple illustration I did for Mamoyan just as well~
