My mother has this plant at her home. It produces the most vibrant yellow flowers, about 1.5 to 2 inches in diameter, with long, oval and smooth leaves. We cannot figure out what kind of plant it is. I recreated the flower in Blender, with an abstract background, then did a lot of further processing in Photoshop to mix an organic, painted style for the flowers with a sharper, geometric background.

This version without major editing in Photoshop. Just a little color adjustment. The flowers and the backgground were all created in Blender.
