Ethan's father Gerald told Fox News : "He was a kind soul, who accepted everyone for who they were."
His friend, fellow influencer Ava Louise, also posted saying she'd lost her "best friend in the entire world".
Both have said that Ethan was struggling with addiction, but his official cause of death is not yet known.
My best friend in the entire world, my twin flame.....the only person there for me when I had no one. I love you Ethan, I am at a loss for words. I wish I knew how bad it was. I know what you’d want me to say to the Internet rn but I’m to heartbroken to say it. Rip ❤️ pic.twitter.com/EjQdm0JVxE

Ethan had over half a million Instagram followers and 139,000 YouTube subscribers.
A Vice article last year described his makeup style as "characterised by its desire to catch your attention" and "dramatic, emotional and, at times, gory."
He started young, saying that by the summer of 2017 he'd hit 100,000 followers and left his private Christian school because his social media activity "[violated] their moral conduct code."
He moved to an online school instead and had recently started his own clothing line called Hellboy.
rest in peace ethan @trashqueenethan you were so incredibly talented at such a young age. i know he’s made many many mistakes... but to say he deserved to pass away is horrible and inhuman. i pray for his family and loved ones, a horrible loss 💔

There was some negative response on social media after news of Ethan's death broke.
He had been accused of racism and transphobia in the past.
But fans also spoken in his defence - including one of his inspirations, fellow makeup artist Manny MUA, who posted: "He's made many many mistakes... but to say he deserved to pass away is horrible and inhuman."
His friend Ava Louise blamed his death on addiction.
"If anyone talks negatively about my friend and his actions over the past year he was battling addiction," she tweeted.
"Speak positively of Ethan. He was an artist & inspiration. So talented."
