The other two images are symbolic, not literal. One is a symbol of trust, another an image of a desirable place to live but is presumably not literally some specific place you are promoting. The feel good, pretty symbols draw people in. If you want to represent a contract, fine. But trying to share a sample instead of the idea of doing the paperwork is jarring and feels overwhelming and offputting. I used to make my husband read all contracts and fill out all papers. If I want your service, it is because you will spare me the trauma of piles of paperwork.

Maybe a picture of a building, followed by a handshake followed by keys in hand? To tell the story without words? But don't remind me of the paperwork. Find a way to tell me you are the person who will spare me the pain of the paperwork, because I don't fucking want to do the paperwork. That's what I presumably am paying you for. So show me imagery of how easy and painless this is, not imagery of torturous paperwork.

Just my opinion.

Best of luck.
