As he was receiving his titles and studied, Benca continued to paint and exhibit his works in many galleries around the world, many of his paintings ending up in private collections.
Popri štúdiu a získavaní titulov, Benca pokračoval v maľovaní a vystavoval svoje práce v rôznych galériách po celom svete, veľa z jeho malieb skončilo v rukách súkromných zberateľov.
