Once in a Blue Moon

Once in a blue moon
you will see her silhouette
upon the roof top
her goestly blue figure
in her long black dress
glowing in the night.
Some say she is old
other say she is young
Some say looks delicate as a flower
and her eyes filled with sorrow and sadness
no one knows what for or the reason why
but once in a blue moon
when the lady walks the night
her legand lives on.

I really don't know. it is totally random what I wrote above to be honest. the pic I spent about a total of 2 hours on. I whould have been writing a research paper when I did this but I needed to draw. Medium is prismicolor pencils.
oh, and by the way, this actually is a serious picture so please refrain from "oh she looks like an ompa-loompa" or "she looks like a blue-berry" type coments. It is better to not comment at all than make those types of remarks
