Great demo! I think your best voice is 0:55! Holy shit dude, do more of that voice.
Other comments - I feel like most of your voices/lines were read "normal" if that makes sense? There wasnt alot of stuff that pushed the limits of your voice or showed off the range you have. I feel like youd benefit alot from re-recording this and adding/changing some adjectives n adverbs to allow for room for some more limiting/challenging ranges
