It takes a lot out of me to draw even little pencil sketches like these. Drawing is hard, but I know it helps me grow and I should challenge myself from time to time.
On a side note, I'm liking the celestial blue background very much. They are "reject" paintings that I covered up with prussian blue watercolor and then texturized with salt.
Give me an abstract watercolor background to paint any day!
Give me a pencil/ask me to sketch and watch me go running out the door! Haha.
What medium do you find challenging?
