Yep. Our very young alter Edward returned recently and when he is here, there's a very odd perspective change. It feels as if he is used to being a very tiny child and we're huge now (from his POV). So although he's looking at the same things the rest of us do, there's a somewhat dizzying quality about how way up high we are maybe. Things are definitely off, like he can't quite shift his vision fast enough as he turns his head so there's an after-effect? It's kind of trippy actually. This doesn't happen with Adam, who's younger, but Adam has been awake for at least two years now, perhaps longer.
I've noticed that colors are brighter, or more vivid, for virtually all the littles. Perhaps it's their sense of wonder that makes them so? It's hard to know for sure, but my experience when they're in front and I see things through their eyes, colors definitely seem more vivid, enticing, pure, almost the way cartoons are? (Hrrm, they do watch a lot of cartoons collectively

) This doesn't seem to have diminished over time when they're out front, even if in my thinking they must have less wonder about things they've been looking at for months to a couple years. But they keep noticing strange details in buildings or tree or anything around us that I would just never think to focus on or would never register for me. I realize this is mostly just because they're children. I certainly don't dead stop in my tracks and stare at whatever happens to peak my interest for a long time the way they do. I suspect their eyesight may be marginally better than mine still and they can see more details.
I've also experienced a hyper zoom in thing once or twice but I can't recall under what circumstances or who was involved. Probably one or more of the littles or Sphinx, when he first stepped back in the body.
