How strong do you usually make jello shots?

I made some for NYE, and half of the liquid I used was vodka.

I could taste that there was liquor in them, and. I didn’t see that as a bad thing, but the friends I shared them with thought they were too strong.

I know that means that I should dial back on the vodka next time I plan on sharing them, but I want to know if I made them unusually strong.
