Continuity mistake: When Mac first shoots up the jungle, he runs out of ammo. From the behind shot the barrel of the mini gun isn't spinning. Then, from the front shot when Mac releases it the barrel is spinning. (01:46:25 - 02:46:30)
Continuity mistake: When Mac calls to Dillon about the scorpion you can see that there wasn't one on his back to begin with.
Continuity mistake: The bullet riddled tree that Poncho is hiding behind changes. It goes from severely riddled to not as much damage.
Audio problem: While a cool sound for the movie, the electric motor powering the M134 mini-gun vastly overpowers the sound of the actual gunshots from it, essentially making it sound like a turbine engine instead of machine gun. Plenty of videos available show this is impossible.
Chosen answer: Yes. The predator can be seen not in the immediate shot after, but the one a few seconds later as they are seen walking away.

Before or after Ramirez gets hit in the face with the branch?
About 3 seconds before. If you look VERY closely (probably needing to pause the screen around 00:40:55 - about a minute after Billy said, "There's something in the trees"), there appears to be a transparent image of The Predator in the background above the major's (Arnold's) right shoulder. If this is meant to be The Predator, its body is curved around a tree trunk and its arms are extended toward the right of the screen (near Arnold's right ear), camouflaged as green leaves.

The Predator - in a recognizable form - really wasn't visible until another minute later @ 00:41:55 when it was on the ground approaching Hawkins and the woman.

That's a tree, not the predator. We see Billy and Dutch head on in "predator vision" as they're talking, which means the predator is directly in front and slightly above them (unknown distance). The thing you're referring to would be in the wrong position.
No, it can't. I've just been through this several times and the predator isn't shown on screen at any time during or just after after the conversation.
