At first glance I thought this might be a photograph.

Yeah it got me too

How is an airplane an original character?

Also removing no humans tag, the pilot is right there

Agreed. Removed the tag.

The waist guns are missing.

Looks like a B-17G. No marking or insignia either.

It actually doesn't look like any variant of the B-17. At best a mix between an E and a G. It's missing the waist guns of later models, but the earlier versions didn't have a chin turret and had blisters in the waist. The lack of any paint or rivet detail makes it look a bit odd too, though the Pixiv comments all seem go on about how realistic it looks...
