I wondered this too, so I started looking at professional snow sculptures. I was paying particularly close attention to the railing and the long steam stack. I didn't see anything quite like the level of consistency and delicacy on that railing. There's some unbelievable shapes in the pro sculptures, but those shapes seemed larger than the boat, the general scale of the boat seems comparatively quite small. I'm highly skeptical that snow could be made to do that. Its possible that the pic could be the front yard of like a world class snow sculptor.

the house shape is weird, all the vertical lines are off

I did some googling. I believe I found the source of this image. The source was a 10 second AI generated video with the snowmen talking to each other. This seems to suggest this is AI generated however I will say there is a small chance the AI video was generated from the image and not the other way around.

Some additional thoughts:

• assuming this is real and not AI, the creator must be insanely talented. Not just some regular person but likely a known artist. If that is the case the artist likely posted this online to claim credit for their work. However I did not find anyone claim this work when googling for this.
• not only are the number of shovels suspect but one shovel appears to be defying gravity while one of the shovels isnt a snow shovel but a "regular shovel"
• the ocean current design around the door and ship is insanely detailed. Again if this was real, this would be a masterpiece, so it begs the question of why we wouldnt be able to find someone claim the work.

A real person would have gotten tbe right kind of door.

I mean just look at the house on the right. It’s build at an angle lmao

I think it's AI, but rops if it's not. Still funny either way

For all her luggage? I doubt it.
