I guess I'll go ahead and share mine since we are allow to now. Hope to see others as well here!
I wanted to do something in the style of those retro "Greetings from" postcards while making it look old and dated like it's gone through a journey to get to Geralt. I picked Kaer Morhen just because I loved that shot in the SoD trailer where Geralt is looking out over it. It's so majestic, even in its state of disrepair. Really looking forward to going back there in Witcher 3.
