Your speaking voice is really good. It’s a common Flowey voice and we like the voice cracks and different inflections in the voice (good highs and lows). We’d be interested to see how you could portray some serious emotions with it. It kind of at the moment seems like you're just doing a voice rather than breathing life into a character, but it is a good Flowey voice. Singing, isn't terrible, you're often off-key in places, and since this is a musical and not "let's dub undertale", singing is important. We'd recommend working on your singing and maybe having another go at the audition. Thanks for auditioning!
