I think you have a good idea in mind, but you would need to approach this in a careful manner. Your building does look amazing, and I think it can be good. Here are some suggestions to make sure it complies with Roblox’s rules, and that it’s handled well.
Roblox does state in its rules to avoid shocking, real world tragedies.
"1. Overly violent content and/or content related to tragic current events or circumstances. We do not allow such content, including:
- Atrocities, massacres, and other shocking real (or pseudo-real) world events; and
- Extreme violence, physical or psychological abuse."
I would suggest removing the fire, as many devforum members have suggested. I think if you built the World Trade Center before it was attacked, it would be more likely to comply with Roblox rules.
I also suggest adding a warning, in case someone may not want to hear about a tragic event. If you want to retell the story, I could suggest adding a rock/area that says what happened, to educate people on the events, and act as a memorial for the victims of this event.
