Two New Covenant Stills

 You cant fool me android

maybe the scars indicate that david has managed to take over / impersonate walter. late in film?

Could be, as one of the Advanced features of Walter is the ability to regenerate skin if i am not mistaken, so maybe this could be David?

The shot of Daniels is interesting, this has to be some kind of Crane on-top of the Transport/Cargo Drop Ship.

Would be funny if that shot of Walter was really David as he assured Daniels and Tennessee the ship will be fine now as he tucks them into sleep. 

Weren't the bandages on his left cheek in the first image which showed the bandages?

Yes, here is the news:

The year’s most terrifying cinematic event happens in “Alien: Covenant” on May 10

 @Roger55 are you sure that isn't a typo?

I can't see anything mentioning the date has been shifted forward a week. Correct me if I'm wrong. 

I enhanced the images, thanks again for posting David 7.

I say the three scratches on his right cheek are not from a xenomorph. You don't get off that easy...the scratches have to be from fingernails.

Dammit Ingen you beat me to it. I was just going to up a brightened pic of Daniels. ;)

I ground my own coffee this morning and it is as black as David 8's artificial heart Tiwaz, so I had a momentary burst of productivity.
