Hey man, appreciate the differentiation in voices, and do really like the Shapiro voice. I’d consider making a much shorter demo with lesser lines that show your range; without the “meme” stuff.
#3, #4, #5, #7 were your best. But would refrain from using poop/shitting as hard as it is to avoid haha
Also consider looking into doing sfx / sound design / royalty free music to have a background and transitions.
