Mom's Birthday

My mom loves Sunflowers, so it only follows to draw her a picture of a sunflower. I have been learning about pastels recently so I decided to give them a shot, I chose to do a monochromatic drawing using yellow as the pop color, I wish I could have had a purple ground to use complementary colors but I don't have any purple pastels, ahh budget of an artist.

This is a piece that I have chosen to sign on the back because a signature on the front would compete  with the composition.
