Demo Reel 2015 Try to express emotion and character action a bit more convincingly. Raising or lowering your voice is certainly necessary to convey certain aspects of a scene, but it takes a lot more than that to really capture emotion in a voice. Unless you really try to put yourself into that scene rather than just reading off your script, your character's voice will come across as hollow and unconvincing.
On a similar note, sound effects and vocal styles should explain enough about a scene that the dialogue doesn't have to outline everything for the audience - it feels like you're almost afraid to let the story tell itself. Let loose a bit and trust in your ability to act, and your scenes will feel a lot less rigid and inauthentic.
As far as voicing characters, if you're going to have multiple characters interacting within a single scene, I'd advise either making a much more distinct change of voice to emphasize that you're switching characters, or have another voice actor (or actress, in your case; you never want to have another actor of the same gender as yourself voicing a character within your reel) voice one of the other characters. Without a clear change of style, you risk your characters all sounding alike, as your initial scene began to.
Best of luck. I look forward to hearing your next reel.
