I am honestly not an image expert… I tend to degrade everything to Macros…
The best I can suggest is to look at the images primarily here: The Official 4o and Dall-E image Megathread
And optionally here (It’s an older thread no longer active - but very relevant as the same model!): 4o ImageGen: Share your best pictures
I post my ‘Macros’ here as some kind of ‘key reference’ though there are many better artists than me…
Use their prompts as a reference…
Better still… Recognise them and ‘like’ those who add real value… That is ultimately what drives everything forward… The understanding of what works.
Add to the threads too… You are clearly interested in this and contributing well!
Indeed… Ask questions too… You will be redirected if off-thread to the appropriate space
