I think we are all confused on what the purpose of needing a description of this is. You say here that you needed to focus on the contest rather than describing this picture. You also mention that this is time sensitive in the OP.
Going off of what Granola said, was this associated with the contest or not?
If it was - pretty shitty to pawn off your writing process to others. Especially after mentioning ChatGPT and all that its use implies. This is a writing site and using AI is a lazy/ cheap way to write your stories - this is obviously pretty FROWNED upon and you deserve all the SHAME you get.
If not - your backstory into why your asking this because you ran out of ChatGPT credits or whatever, coupled with "with limited time left..." really implies that this is for the contest. I don't see how you could play this off as not being apart of the contest. If it wasn't you could have just led with "Hey guys I used to play a game and this was a scene. Here's how I would describe it: blah blah blah. How would you guys describe it?" At least like that, you can get people involved and start a conversation and get creative instead of "Can't use ChatGPT, how you would guys describe this?
Would like to note, how the hell would your mind fill in the blanks if people are giving you a full blown description of the picture? What blanks are still there after someone describes it to you?
Another follow up, your justification doesn't need to be complex. You could literally just say "I was bored and I really like this picture".
Yes, the idea that it takes time and energy to come up with a description makes perfect sense because that is the point of it. It's not suppose to be easy.
ALSO ANOTHER THING, I don't understand how describing something you are "over familiar" with makes it difficult to "describe with words". Shit just start with the five senses. Its alot easier to describe my own home than the home of a stranger. Not everything needs to be described by sight, throw in some feelings the character feels when at this location. Does it have a particular scent? Can you hear the fire crackling on the pillars? Is the platform moving? Does it feel like an elevator? etc. Don't limit yourself to 1 sense when describing pictures. This is what ChatGPT will never be able to offer you.
