A few more hours work done on this over the whole piece and this is a pretty accurate representation of my drawing. It's quite difficult to get strong colours on this particular grey/green pastel paper. I do work with fairly light strokes and do not layer heavily as I like the subtlety of colour that this technique produces but, even so, I can usually achieve rather more strength of colour by this stage in the work.
I shall continue to add more of the same colours. I'm using probably all of the mid and dark greens in the Prismacolor and Derwent Coloursoft ranges in that foliage - I think the Coloursoft pencils suit this paper better because they are more chalky than the Prismas.
I'm impatient to get this one finished now because today I had a flash of inspiration for a new white still life set-up. I'm charging up my camera batteries as I speak in readiness to take a zillion photos of said new composition!
