Hello everybody!
I did this painting for my astronomy class, the project was worth 20 points(i got full credit :P).
This took me about two hours to do and i'm fairly pleased with how it turned out.

I used Crayola watercolors and a white gel pen to make this, along with black acrylic paint to do the trees.
The brushes I used were a flat wide brush, and a standard thin pointed brush.
