Good observations @ WesleyBPeres. I had to charge my HTC Radar to confirm how live tiles perform on it. Below are my observations about photo tile.
1) The pictures in your top two screenshots are of selfies in portrait mode. Your live tile in landscape mode (elongated rectangle). I tested the same on WP7 and it displays the same way as your screenshot.
2) The live tile is designed to just show glimpse of what is your photos folder/favorites. It also has transition affects that zooms out. Hence you see the cropped images on your live tile.
I agree to rest of the things you noted about the space on tiles. The space on tiles could be better managed.
1) Calendar - Show multiple events as a list
2) Alarm clock - Show alarm clock tile with animated clock on it.
I decided to go back to WP8.1 Denim after a problem on last Insider build (

I agree with you about the self ones, but look at the comparison with the same photos. The WP8.1 knows where "to look" in the photo to get the important part. But W10M just looks at default points.
Two screenshots cause WP8.1 starts from above and goes down.
First photo that I got a screenshot on W10M, we had my hair and forehead. Now we have my face in focus.
The second photo was too zoomed. This one on WP8.1 is not too zoomed, but yes, it's really near.
The third photo is good in both OSs.
Here we don't just have the head of my girlfriend, but the hole body.
Something is really wrong with the Photo's Live Tile in W10M. The problem is that in W10M the Tile is focusing in the wrong place, I mean, if the camera app have something like "finding faces", why the Photo's Live Tile appears to start in specific points and not the most important ones?
