I absolutely love the golden city one. Imaginative, creative and stunning. The colours and the amount of detail is very good. The other one however is boring yet simple. Shows three people on a warthog however I love your first one.
I forget the name, but it was in odst on the level where you play as dutch and drive around a lot. It was like a zoo or something, but i got out of the map and found this place and took a picture.
Its uplift reserve, I really like the 1st one, I've seen pictures similar to it, but never with the city in it as well 8.5/10
