The best accents I use often, and can supply with ease are, British, Italian, German, Russian, Japanese, French, Southern, Australian, etc etc
As for impersonations I can do a variety of different impersonations. From famous actors, like Kristin Chenoweth to Disney's own Maleficent. For instance, I can do such impersonations as Shock from The Nightmare Before Christmas, Mitsukuni Haninozuka from Ouran High School Host Club, Hermione Granger from the Harry Potter series, Seras Victoria from Hellsing, and many others.
My wide selection for characterization lies in the hands of the client. They ask for what ever they desire and I shall try my best to give them what they wish. I can be an anti-social angry teenage boy, a happy and good-hearted young girl, a mischievous and clever child, or a wise and calm elderly woman.
