Margaret Shaw - Artwork - WIP My Flowers

I was pleased with the flowers I had in my garden tubs ( June 2018 ).  With the hot weather and watering they were quite profuse.  Wanting to take something to the art group to work on, I took a few photos with the intention of doing some small pastels. My Begonia worked out well and is framed.  My Lillies and Pinks got abandoned.  I prefer the single flowers.  Wanting a triptych a rose and an iris have moved onto the easel.

Irisof complimentary colours

Drawing

Worked petal by petal from top to bottom of flowers.

Background was added with several changes along the way - this one is in the thinking pile.  Do I try to do more with it or maybe re-start with close up of middle of flower?

A stunning single rose

Drawing

Pastelling started - working petal by petal with careful studying of the reference.

Rose complete, background colours marked in and blending started.

Background blended and darkened the dark areas in the flower.

Framed to protect the work

A bit of photo shop editing showed up the colours in the white begonia
