There is not one item in the poster that is a direct link to Rhuidean. Everything you suggest is pure conjecture. You cannot even be sure that it is not evening rather than dawn in the poster or the trailer for that matter. IMO the shot from the trailer looks more likely to be the arrival at Rhuidean meaning the time could be either morning or evening. The ground in both shots is also completely different one is a desert the other is hard and rocky. Any attempt to state that those 2 locations are the same place is simply a fantasy that you are building in your own mind. Yes i am aware that the poster can be entirely different media and i would posit that we will never actually see the poster shot as an exact scene in the series. The wide open scene with a circle of spears apparently in the middle of nowhere seems a highly unlikely in show shot.

Look at the distance to the sand dunes in the background. No way that the city fits in shot 1. Look at the ground, one is hard and rocky the other is a desert. Both shots do not have mountains in the background one has sand dunes.

Rubbish, pause the trailer at the 1 second mark and you can clearly see the massive differences between the shots. There is no way those 2 shots are at the same location. You can argue that the other shot is better if you want but I will heavily disagree with you and I don't see the problem with giving the book fans an iconic shot to get excited about.

No Rhuiedan He is walking downhill. So wrong direction No fog covered city. No one waiting for him. Not sure how you think this is showing he who comes with the dawn leaving Rhuiedan The Visual of the city in the fog with Rand emerging from the sunrise striding to the waiting Aiel leaders is just simply a far more powerful one.

Still cant believe they did not use Rand walking out of Rhuiedan carrying Moraine as the S3 poster. Such a better visual plus awesome for the fans to see He who comes with the dawn.

Firstly why did they not use the first shot of the trailer as the season 3 poster. Remove a few of the people and have Rand carrying Moiraine towards the camera and that is a much more powerful poster. Not a terrible trailer but also not much meat on it either. Loads of quick jump cuts with little dialogue.
