Screenshot (forza)

Hello. I make a small post to ask a few questions.  
Is it authorized to post screenshot of art we make in game?  
For people who make design in Forza, can we screen the car with what we made and upload it on the site?

If the art is original, then sure, Forza is just the medium it was made in.
 
If it’s existing art “pasted” onto a car, then we’d prefer to just have the original.

And if it’s to show a car with pasted art on a car, and a specific design for the car like;

would that be allowed?

I suppose it would be fine; what we want to avoid is “spam”, something we saw on derpi with Forza, World of Tanks, and some other games where the same paintjob on a vehicle would be uploaded in 30 different camera angles or situations.

Ye I understand. Thank you for your answer.
