"Houseplant" Colored Pencil Drawing

"Houseplant" 5x8 colored pencil drawing

This is a colored pencil drawing of a house plant that I did thirty years ago. It was drawn from life. I never finished it and, from time to time, come across it again as I leaf through this sketchbook. Each time I admire it and feel that it has potential. 

Maybe it's time to get out the colored pencils and actually finish it. Only one of the leaves has been burnished with a colorless blender. How will I complete the rest? That is something to ponder. 

I no longer remember what kind of plant this is. I only know that it was one of the few houseplants that I couldn't manage to kill through neglect.
