Psykhe is the greek goddess of the soul. I prefer to have a style that embodies the dark beauty, drama, femininity, luxury and mythology into my style. While I am a photographer, I do not wish to incorporate any sort of camera/lens into my logo.
The design/symbol should consist of a butterfly, as it means/symbolize's the soul in several cultures, please think elegance and sophistication in the design, nothing that could be labeled as sweet, cuddly or cute.
I also may like a circle or an Ouroboros encircling the butterfly.
Please check the references as to the design examples.
For the font name of PSYKHE, think Chanel font, but for the slogan to have a little more sophistication and not as bold. Please, add the 'Ψ' to the 'Y' of the name, as it is reference to the name.
