Doesn't look too bad, though your stats look a bit weird. For future reference you don't need to specify your racial bonus as it's own thing; if you have a 16 in your charisma I'm aware that it's from a racial bonus. Just helps clean up how it looks.

Not sure where you're getting your extra cantrip ability from. Tieflings already have Infernal Legacy to give them a smattering of spells, Thaumaturgy being their innate racial cantrip. If you copied off Papa's CS, they can merfolk gets to choose a cantrip thanks to a racial ability.

Entertainers are proficient with Disguise Kits and one instrument of their choice. I don't mind if you want to be proficient in two instruments instead, but two only, not three.

Lastly, do remember that the entertainer background does give you a background feature. Being that you're a level 0 nobody, such thing will be important for RP and future purposes. Put that feature down in your trait section.
