The Embers singer has also stood by his Eurovision performance, saying he “couldn’t have done any better”.
The UK entrant wasn't about to take the criticism lying down.
James became only the second UK entrant in Eurovision history to score zero points at the contest this weekend.
It's only the second time ever we've done so badly at the Song Contest.
The Embers singer hopes his belief in positive thinking can carry him all the way to Eurovision glory.
It was previously revealed James would be returning after he was originally meant to represent the UK in 2020.
The 2021 Song Contest will take place in Rotterdam in May.
Listen to the song by the brother of John Newman, who has previously written for Louis Tomlinson, Little Mix and Ed Sheeran.
