冯贤哲 (Vincent Feng) is a Chinese artist, so it is unlikely that he has an English nickname. If you are asking for the English translation of his name, it would be "Vincent Feng". However, if you are asking for a shortened version of his name in English, it would depend on the context. Some possible options could be "Vince" or "Feng". It's also worth noting that the use of nicknames or shortened versions of names is not a common practice in Chinese culture, so it's possible that Vincent Feng does not have a commonly used nickname in English.
