From just seeing his appearance, my first impression was that Yorick might sound a bit like Ignis from FFXV!
Okay, I thought this might be a fun forum game. Or not. I dunno.
So what you're gonna do is post IC and choose a voice from a show/movie/cartoon/anime/video game, etc. you think the character posted above you would sound like! You can base this entirely just off their design, or read up on their personality if there's a big description and kinda go from there [although, if they already have a voice match descripted don't read it just come up with your own, at least just based on the design in that case]. It's up to you! Try to link to a clip of the voice too, on youtube or something and link it in your post.
It doesn't have to be exact of course, just pick something you think would fit. I love voice matching my characters so I personally think this would be fun :0c
Anyway have at it have fun!
