I too am incredibly sad to hear this.
A gifted, generous, and prolific teacher and artist is lost.
I never had the privilege of meeting him in person, but I heard very nice and inspirational accounts, which very well resonated with his fantastic and sometimes bold artwork.
It's a sad day for this world. Many have lost a friend, family member, mentor, or source of inspiration.
My thoughts are with the Prifti family, and I offer my very deepest condolences as well as respect.
