It's about the 3rd edition of the Cup Competition organized by Federação de Mockups. Unfortunately it's not about the 3rd place in this competition, I lost in the last 16 round. The competition had a theme based on a music competition from this site: http://www.vagalume.com.br/.
My team was Rock Nacional Classico (Brazilian Classic Rock). The only starting point was the crest, the design is based on it.
