[WIP] Insurance Company Logo

First concept/sketch for a logo I'm doing for an insurance company. The idea is to represent the labyrinth as a demonstration of security (since in portuguese the actual name for Insurance is 'Seguros', with means security/safe), because in old Greece's mythology, the labyrinth was created in order to protect people from the Minotaur, which was, in some ways, a representation of something bad.

The labyrinth's composed by the initials of each word as you can see in the attachments.
