Botanical Work in Coloured Pencils

I'm really enjoying my coloured pencil work at the moment and am making good progress, getting a feel for the techniques and colours.  I'm doing sketchbook work as well as finished pieces.

These are some of my completed exercises worked from my instructional books. This one is an exercise in depicting 3-dimensionality from 'Classic Sketchbook - Botanicals' by Valerie Baines

This one is an exercise on shading white flowers on white paper, from 'Botanical Drawing in Color' by Wendy Hollender. I'm fond of Ox-Eye Daisies so I'm going to work up my own drawing now that I've got the hang of the shading from doing Wendy's version.
