It's fine. it works. The possiblity of his voice being softer then I imaged is something that's been floated. I suggested if that's the case it's like Chris Pratt or Ryan Reynalds.
I've been championing Ron Perlman, Mark Hammil or even James Earl Jones since he was shown to still be alive. I think there voices still could have worked with this character at least the first two (Hamill could have used a voice more similar to Luke Skywalker then Ozai or the Joker with what we're shown), Jamie Camil works to constrast Shastacan's upper class, stuffy and unpleasent voice.
Globgor sounds gentiler and more welcoming then Eclipsa's fat fuck of an Ex-husband.
