These pieces are by Anne Ten Donkeelar, and she has used pressed flowers, arranged carefully on pins, to create very beautiful, delicate 3 dimensional collages.
These paintings, by Mercedes Lagunas, appealed to me due to the colourful and abstract nature of the art. They have some geometric qualities to them as well.
I also included these images by Dee Dee Cheriel, because I really liked her geometic designs, and the hand drawn, illustrative quality they possess.
