I think this thread could be greatly enhanced if you were to share the progression of AI prompts that you used to get there, and the intermediate output images.
I'd love to see the outputs of your queries if they didn't include some of the phrases that you ultimately included.
For instance, how did it look before you included "dorky smile, clean shaven, chubby athletic" in addition to "chunky athletic guy."
PS: I assume Dean is athletic since he "usedta could" touch the crossbar of the goalpost.
