I would like to see Danyl leave the competition now. It's clear he has talent, but he needs to go away and really work on his delivery and his overall attitude - especially his facial expressions - and that's not going to happen between now and the final.
A few months spent watching his own performances and getting into the right mindset would really help him to portray a sense of being authentic, instead of these scary smiles he produces (or when he was dancing, a kind of intense stare). A good singer needs heart and soul in addition to their talent.
