I'm pretty sure the rock is in a similar spot, the camera is just not in the same position because it's two separate runs made to look as similar as possible.There's certainly some differences between the two screens but that is because they were taken from both the English and the Japanese builds (command text, MP/Health bars) so I'm not sure if we can deny that the amount of water being the reason for the lighter model. However there are some things that are actually different between the two images, such as there being a rock underneath Sora in the Japanese screen.
I understand there's bound to be some difference between them, it just seems a bit much imo.
I zoomed into both images and flipped back and forth, there's a definite difference in saturation on Donalds tunic, Goofy's goggles, Sora's eyes, and Flynn's face but like I said before that could be from added compression by 4Gamer.I'm not seeing much of a difference on the HUD icons. What I am able to see is very minor, but that may just be my eyes.
