Hmm. Using Bing, I definitely do not have access to settings, I can only change my input to be longer and more descriptive of my idea.

In Bing Image Creator, DAL-E 3

Prompt: a Hawaiian shirt with a normal palm trees, bright colored flower blooms, and white background design.

It seems to have taken Hot Wheels as meaning the cars rather than the logos. But it’s a lot better!
