Good approach regarding it simple (I myself am a User Requirements Engineer and UX expert). However, this feature is rare to find and those who offer it don’t deliver good results. I guess there would be a market for it and so a outstanding feature for you: Often I find images and think „Wow, how to generate this?“ But them it would be so much work to describe everything! If there was a feature that could do this work.. and maybe even identify the aperture etc. of the shot.. awesome! So let’s hipe and see what the future brings..

Regarding the UX: It would be great to have a second „generate“ button below all options you can select and put in. I work a lot on mobile and after having finetuned everything I always have to scroll up and back to the generate button. So why not placing it below the advanced options? 😊

Best regards!
