So, my game was rejected for next reason:
"Your app or its metadata appears to contain misleading content.
Specifically, your app includes content that resembles Illumate without the necessary authorization."
Illumate- russian artist, the game is about him, I use his image here.
Then app review team said:
"It would be appropriate to provide documentary evidence that you have authorization from Illumate to use his image in your app."
I don't understand, how to get this documentary evidence, how it should looks like.
