I finally gathered all the votes together and made five, god-awful fanarts. Don't blame me. I'm really tired :P
And if there's like a slight mistake in the amount of votes that each couple got, I wouldn't be surprised, I suck at math, but I think it's right.
As you can see, it's a lot more than 20 (all of the nominated ships, actually), but there were a lot of ties:
