Definitely a couple of aspects I really like. The color of the voice could work quite well with Ripto I think and the dirty laugh supports that too. Your audition sounds very British though as opposed to the General American accent that Ripto is mostly speaking. Also, Ripto sounds fairly angry at almost all times so that's something that could still be conveyed in the audition a bit more since you were speaking quite calmly. I'd be interested in hearing another audition from you though!
