原作 (gensaku) specifically refers to the source material of an adaptation (e.g., the novel a film is based on). オリジナル (orijinaru) is broader and can mean 'original' in the sense of 'not a copy' or 'unique'. For example, an 'original screenplay' is オリジナル脚本, not 原作脚本, because it is not based on prior material.
The phrase 'original work' can be translated in many ways depending on context. Using オリジナルワーク (orijinaru wāku) is not natural Japanese. Choose the appropriate term above.
