Just out of curiosity, where it says “o Select photos will be featured as Forza Motorsport 6 Turn 10 picks for a period of time. (Until the next contest winners are chosen and featured.)”
Where are these Turn10 Picks displayed?
I find these photos and many more through the FORZA HUB. Either in-game in the Gallery or the Forza Hub app on Windows 10.
Just out of curiosity, I’m wondering if there’s a way to tell which photo of mine got the unicorn Aston Martin? I’ve checked the turn 10 picks at the hub, none of my three entries are displayed, and it stated they would not all be, so I get that. I’ve looked at the photos and their ratings, none seem to have anything different noted, or marked, or have more stars under them. It’s not a big deal, I’m tickled to have the car, just wondering which they liked enough to reward with a unicorn.
Usually, I can determine which photo was a Turn 10 Pick is when it appears in my Gallery with FIVE-STARS 
I’m curious if there is anyone who entered and DIDN’T win. lol
Maybe since FH3 is coming out soon they wanted to go out with a bang and hook everyone up who participated.
If that is the case then I hope they do one more before Horizon 3 comes out haha, only one more to go for me!
