In keeping with our mission to highlight talent, future iterations will allow users to submit their digital art for the theme gallery. This new take on self-expression through design will incorporate a new robust theme machine, enhancing the ability for partners and users to create specialized profile designs for musicians, celebrities, brands and anyone else who wants a unique design.
