Masterfully done. Nice use of the syntax. My only suggestion would be to enclose your ALL CAPS attributes in braces, they seem to be functioning as Aspects with Aspects within them (which is perfectly allowed in XBasic

), so you'd enclose all of their contents in braces. Example
HEART{
<starving child>
Mask {
<termite-eaten oak - concealed by a layer of strong bark>
<depths of an overcast sky>
<shiny, polished armor - empty inside> }
Vulnerability [
<60% - hidden by a network of lies to himself and others>
<a door to which the owner has lost the key>
<soft pink sky of dawn hidden by a rolling thundercloud>
<a single violet>
<Song for the Broken ]
<a prisoner - bound and gagged with lies for ropes>
<a prison with bars of cobwebs>
Desire {
Love [
<mourner>
<hollow wedding cake>
<late but refusing to ask for directions>
<child in "Flywheel">
<toy wagon with old, chipped paint>
<abandoned crumbling 1800s farmhouse>
<prisoner 24601> ]
Acceptance [
<slaving for a good grade>
<Rameses in "Prince of Egypt">
<dust in the bottom of a dry water jar> ] }}
As for the "better name" for Outward Appearance, there's a word that matches exactly what you're trying to say....and for the life of me I can't remember it

Composure would work, but I'm not sure that it's the word I was looking for. You could also use "facade". Hope those ideas help. Keep up the good work. Oh! And on my computer, I had trouble reading the Body because of the font color.
Again, awesome work!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
In Christ,
