I tried to create this from scratch without using any external references. It was harder than you would think!

And only GP1 was able to create the correct tentacles but tended to add eyes to them.

In the end, I created a prompt that resembled tentacles and made that into an image.

Then I used that as a reference to create the rocket scene, the prompt for which I refined over several iterations.

Finally I added the logo in another run.
