Eyeball my pinion angle please!

Decided to take the Jeep to the office today on my hour long commute. I'm still shocked at how smooth it drives!!!

Trying to figure out what could have gone wrong with my initial DS rebuild. The u-joints were all seated evenly. The only variables that I can see in terms of balance being thrown off would have been either putting the double cardan on backwards or possibly the center ball yoke piece (or both)?

I did use some of my wife's fingernail paint when I had disassembled it, but if it was in fact balanced with the DC/CV facing the other way, I'm thinking that might possibly have been the cause?
