Yes! You could also change the post so all the options have a preview like you did before adding the new poll options. So changing "Quick example of this:" to "Option 4 - ... "
Example
Option 1:

Option 2:

Option 3:

Might clear things up as well.
I like the bottom one the best (option 3) for the reason that they have different colours. The colour tells something about the community you're looking for.
A 4th option where you still have the UBP icons, but with the colours as shown in the bottom picture would be a good middleground. (Option: 'Use UBP icons everywhere but with different colored gradients')
just my two cents
Third time is the charm! Post is looking good and new voting system sounds reliable. Thank you for all the effort!
