The text reads:
Purple makes me feel comfortably confined.
IN THIS RUBY RAZOR BLADE DOLLHOUSE
Foundation of my ghost's shadow.
Personally, the colour purple makes me feel warmth, hospitality but also "the state of being trapped" in some strange way.
In addition, every time I think of purple, I am reminded of these Victorian household decorative styles. No idea where all of this is coming from.
"Ruby Razor Blade Dollhouse" is a title for a song I have yet to finish. The vibe of the artwork as I was painting it reminded me of it and so I decided to implement some ideas from that song. It also strangely connects well with my view on purple too. Hmm...
The girl in the picture sympolises, well, how purple makes me feel. Her Victorian clothing is fancy and comfy. However, her wings are tilted inwardly towards her body showing that, while she can be free, she prefers to keep herself in this enclosure... or maybe she is forced to be kept in place. That is not made clear on purpose, but you get the point.
The window on the wall is trying to convey that the girl is being watched or even controlled (like how security cameras work), perhaps another reason why she cannot leave this place.
The bright red triangle with the splash of red on its upper point indicates injury and yet balance within such violent circumstance.
The sentence "Foundation of my ghost's shadow." is meant to express that the girl created this cage for herself in the past. It also suggests that the girl might have passed away/is inactive as she is a ghost/angel with wings, whereas her shadow is still alive and active due to her lack of the wings (kind of hard to notice in the drawing).
This can go much more deeper, but I'll leave the rest of the details up to interpretation.
