Voiceover impersonations of existing characters

[franciscocronin]

Hello everyone!

I'm brand new to Fiverr and creating my gig to work as a voiceover artist. I do a lot of impressions of existing characters (like LOTR, Futurama characters, etc) and I am not sure about the rules and taboos of marketing this? I see a lot of people marketing their impersonations of real world people like Morgan Freeman but I don't know how to tread when it comes to copywritten characters. I've come across a few gigs actually saying movie lines in their demos but I feel that they're more outliers than the norm. Any advice?

Thank you!
