I'd like a lucky rat hat myself, but eh.
As far as Tycho's hair goes, that thing is a physical impossibility. It hardly makes sense in the comic, it wasn't spectacular in PAA, and I think it's a valiant effort here.
And yeah, the voice is weird at first. Honestly, after listening to the podcasts and watching the documentaries, when I read the comic, I hear Jerry and Mike. That said, Jerry can sing and he can write a comic and he can clearly be a tremendously funny guy in a conversation but it's quite possible that he's not a verbal comedian in a context where you have lines to read and are addressing fictional cartoon characters with larger-than-life personalities instead of, you know, your best friend since small times and your work family.
Of course none of you are actually saying that Jerry should do the voice, that's entirely my first assumption. But going from there, it's gonna sound weird no matter what. I mean, there was a similar case with the PvP animated series (if anyone else here has even seen that) and the voice of Skull, which was kind of unexpectedly nasal and high-pitched, but it did work eventually, it was just a question of giving it time.
