A pretty impressive showcase. :) Not bad! Not bad at all! That old man voice in particular. Do wonder if you'd be able to extend the range with some entirely different styles though. Foreign accents? Other genders? Younger ages too (you've got the agey age down right)? It's a great showcase for a certain few roles, though doesn't seem to show you can really do 'everything' (if you can ;). Happy 2017 man; good luck with the path of voices!
