ChatGPT can't generate realistic professional headshots for LinkedIn - any tips or better AI tools?

I need a professional headshot for my LinkedIn profile and resume but photographers are charging $400-500 in my area. I've been trying to use ChatGPT with DALL-E to generate one but the results are terrible.

The headshots look polished and professional but the facial likeness is way off. Doesn't actually look like me even when I provide detailed descriptions. I've tried like 20 different prompts and none of them capture accurate facial features.

Looking for advice - is there a specific prompt or technique that works better for generating realistic professional headshots in ChatGPT? Or should I be using a different AI headshot generator instead ?

Someone mentioned trying Looktara instead of ChatGPT because it's specifically trained for headshot generation, but curious if anyone here has figured out how to make ChatGPT work for this.​

Has anyone successfully generated realistic professional headshots with ChatGPT for LinkedIn? What prompts or approach worked, or did you end up using different AI tools ?
