Firefly no sabe lo que es una pieza de Lego

For those type of images you can just describe here I shared my screen shot

As droopydog500 say that Images with rights thus withheld are not used in the Firefly learning.

Hello @Martin Araya,

Thank you for your message. I am sorry you are having this problem. 

Firefly is not trained to create objects covered by trademarks or copyright. LEGOs are trademarked. It is a goal of Adobe that images created in Firefly are commercially safe. It is unlikely images containing trademarked or copyrighted objects would be commercially safe. 

My best,
