"Lilith" sketch by @mihaistirbulescu

First of all, this is not the final drawing. Secondly, I did want to post a drawing of a nude woman for a while here, but I want to make it more interesting, by drawing two greek columns on the sides and a greek circle in the middle above the woman.
I want to make the sky filled with dark clouds and water reflections underneath the woman but it is pretty hard.
I did this with 2B pencils and Staedtler pigment liners on A3 paper.

Thanks for watching,
@mihaistirbulescu
