Tickseed Sunflowers (bidens polylepis) painting

The painting here "Tickseed Sunflowers" was created within 30 minutes or less. I painted this back in September (2014) from a reference photo which you see below. I used acrylic paint.
Yesterday I gave the painting to one of my Grandmothers as a present.

December 2013 Painting of Bird

The picture below was taken of one painting I done in December 2013. This painting now belongs to one of my Grandmothers. I forget the exact dimensions of the painting, but it was something like 8x12 inches using Acrylic paint. The painting was completed within two hours.
