Jerlita Week 3: Xanthene

Jerlita Week 3
Day 6: Xanthene [link]

Look at the stars,
Look how they shine for you,
And everything you do,
Yeah they were all yellow

This prompt... it was hard to think of any way to execute it. But finally, an idea came. Xanthene is a yellow substance, so I seeked in this way. And I recalled the song "Yellow" by Coldplay, and tried to depict it. This is the result. Jeremie and Aelita gazing at the stars on the dorm's rooftop. Remember episode Maiden Voyage? ^^
I used my experience with Lucubrate piece and did exactly the same trick with mask layer. Also played with layers to get the yellowish color of citylights' aura on the sky.
Do you see any constellations there?
