Just to throw in my 2p;
I have no issues with the voice in general, I generally am not expecting perfection and just take it as it as it comes. However, this doesn't stop me from noticing weird ways in which lines are said or that they don't necessarily feel as emotive as you expect. I can even take a clip that someone posted earlier for comparing EN and JP voices to show what I mean.
The clip in question:

The start, 'Think you're cleaver, huh?' I find fine, generally no issues here.
The next bit, 'I'll rip off that beak...' Again, this bit, fine.
The last bit, 'and roast you on a spit!' This is the bit that ruins it for me. The less egregious bit is how she says 'roast', it's almost there, but more emphasis on the roast would have made it better, but the worst bit is the end, there is a weird pause before she says spit and even how she says spit is weird. It just doesn't quite flow and really stands out as being out of place.
Again, this is my completely unprofessional view, but it is these places where you need to properly articulate the emotion that make the most impact in your performance. If these fall flat, it doesn't matter how good the rest is.
