Berro drew the "Devils Associates" series into a Frieze Magazine from 2015. Fast, energetic, and free, he wanted to bring these creatures onto the paper, as fast as possible. He only had one color pencil and one hour.
"Devils Associates", the title leads the spectator into this devilish world of these mystical and mysterious creatures. They seem disturbed and almost soulless. It can also be viewed as a metaphor for the mega-galleries, that are featured in Frieze Magazine.
A lot of the creatures seem to have sharp teeth or horns, it indicated their association with the devil and his threatening features.
