Impressive stuff.
What can I say bud? This was a rather impressive demo reel. You have a great great GREAT deal of variety between each of your voices, and not one two voices sound similar, they all sound unique, they're all great voices someone could use in a flash, and they all have emotion and life in them, so it's good to see you're emoting well in your voices, you definitely have a knack for performing the various voices well, so nice work man.
My only suggestion, is while you gave a good amount of voices for your demo and voiced as each one for just the right amount of time, I think you could've maybe added a few more voices to the demo to round around 1:10 or around that range, just for genre variety, like action voices or horror, but either way, doesn't matter cause you got yourself a great demo here. Nice work bud. :)
