Reasons for match photo to not work

It’s going to end up as models, and you could replace all the textures too if need be. I’m not so worried about the quality of the photo as a texture, but just to get models that match what the photo implied.

This is the topic that came up that made me think about this, and it is an example where the blue axis doesn’t quite work out, and yet the photo doesn’t look that extreme:
