Considering how thin my Daemon looked, I took another picture, taking more care in looking straight and keeping my head even, as that warped the first impression of my right side.
These ones came out much more flawless, where you can hardly see the any cutoff lines.
This is my left eidolon, which still looks like Gustav.
The left side shows my physical side, where I really like to do physical activities.

And this is my right Daemon, which gives a different impression than the left. And actually seems more like me then the left side, which is likely because I feel more from the right.

This is the photo I took it from.

One thing I noticed with these pictures and other people's pictures, is to notice how warped or unequal peoples heads are. After seeing the right and left sides together, and how they even out the head, the regular shots seems really off proportion.
The top of my right side is bigger than the left and the left is wider or bulkier around the lower cheek area.
I suspect when people have nearly equal proportional head structures, on both sides than they would be fixed in the left. I don't know if someone can have a structure where both sides would support the right.
But I feel if the right is identical or nearly identical to the left, then they would probably be more focused in fundamental physical logic and physical existence.
So I suspect a warped head is probably a good balance, ironically enough.
But I am not sure why we would refer to the right as the Daemon side.
I haven't read the Daemon book yet, elew is reading that, I am reading the itladian one.
So I am not up on what exactly the Daemon is thought of being.
My first impression was that it was beyond form. A discussion with SAB was an attempt to find out if the daemon existed in form or outside, and it wasn't resolved at all.
I would feel the right and left were the eidolon and the daemon communicated more likely with the right side.
