I was really excited when I saw your map in here.

I rarely get to read any Xmaps but my own, except for Patrick's, and he doesn’t really use X+ a whole lot. * sticks tongue out at him *
So I started reading it, and – this is a really cool X...! I love it.

I was nearly dancing reading it, it made the character seem so real to me. I feel like I made him, you described him so well. The map isn't all bits and pieces, it seems to be one person, whole, even when the pieces are a little surprising. (Though there's plenty of room for adding more....

) And your metaphors are really good...
And the character... * thoughtful * .... Suffice it to say he is extremely interesting, and I am not precisely sure whether he is the sort of person I would like to take with me on a quest to dangerous lands, or not. * laughs * Or even if he is the sort of person I would like to shake hands with....
And the tenth layer was surprising to me. * queer look * Even if I wouldn't like to shake hands with him after all, I would definitely like to know more about him....
Just on a note of technicalities, however...the keywords ABSTRACT, ALLEGORICAL, and CONCRETE are not ones that would be used for labels...as far as I have discovered.

They are more pertaining to the actual quality of the attributes themselves, rather than the way in which they affect their siblings, you know how I mean? So
*ABSTRACT <an overcast sky an hour before rain>
would be instead
<an overcast sky an hour before rain – ABSTRACT>
And it would work the same with the attributes larger than elements as well. Like this:
emotion*CONCRETE (
......*45% <a ghost that is unwillingly tied to this world>
......*SUBTRACT^100% <a cat playing with a ball of yarn>
becomes
emotion(
......<CONCRETE>
......*45% <a ghost that is unwillingly tied to this world>
......*SUBTRACT^100% <a cat playing with a ball of yarn>
And, though I am not sure, I think some of the other labels you used might fit your meaning better as bits-after-dashes as well. Like some of the percentages.

Oh, and did you mean the bits in this element – <a pit – an abyss – a void> – to be nested? Or are they simply several words, like synonyms, to describe the same thing?
