[citation needed] Mores was strongly influenced by his uncle on his mother's side, Charalambos Potamianos.
Potamianos introduced him to Vasilios Yermenis who gave Mores a few painting lessons without charging him a fee.
One that influenced him greatly was that of assistant to a goldsmith jewellery maker, a job which he kept even after being admitted to the School of Fine Arts.
In 1965 he took part in the Quadriennale Europa in Rome, and in 1973 his work was exhibited at the Trittle Gasse gallery in Zürich, together with that of painter Lili Weber.
In 1974 he was awarded the fourth prize at Cercle International d'Art Contemporain, Galerie Riviera, Nice.
