Generate a Rainbow Bridge

This technology is incredible, sure. It also seems to be monumentally stupid. A friend of mine lost their pet yesterday. I have pictures and I was going to Photoshop him onto an AI-generated Rainbow Bridge. The problem I'm running into is that there doesn't seem to be any combination of words in the English language to get this thing to generate anything close to what I want. And what I want SHOULD be pretty simple. I want the view to be, quite simply, a Rainbow Bridge arcing off into the distance, flanked by billowing white clouds, and a sunny blue sky above it all.
