It's awesome. But tbh mutsuki looks nothing like yuki. He looks a lot like the grown-up version of momiji. Like when they showed momiji as a tall high school student. But mutsuki's personality is like yuki's though.
Mutsuki's personality reminds me of yuki's after he got contaminated with kakeru's craziness. And mutsuki looks so close with hajime like yuki and kyo in the end of story :3
I also feel that a little bit of his personality is due to his uncle doting on him, because you know that definitely happened.
I like the fact that it the children of the original fruit basket manga characters ε=ε=(ノ≧∇≦)ノ
