Coreopsis Grandiflora

Trying to get into the mode of drawing again, has been so hot outside and ants everywhere. I decided to pick some flowers for the house. When planting this year I scattered some wildflower seed and coreopsis flowers began taking over, they are huge. Very happy in my little garden, however all my other flowers are being pushed around - maybe they like the shade though. I started with a pencil drawing with shading and mixed in colored pencil and thought the effect was interesting, very deep... I like deep.
