Pongtorn was awarded the prize for the composition piece Thrust, which was composed as part of his MA Music course at the University of Birmingham.
The Young Thai Artist Award has prizes in the areas of the arts, including music composition, photography, film and literature.
Pongtorn said: "This is one of the major composition competition in my country (Thailand) for the young composer. I would like to say thank you to everyone who has always supported me since the first day I decided to be serious on this path."
