Finally Finished Cypress Trees in Colored Pencil

Could you sense my absence from the web recently? I've been working, working, working on a colored pencil painting. I am finally finished - I think. I said that last night and signed it. In the light of day, I decided (with my husband's critique) that it could use a little punching up in places, so back to work. Then, I thought it was done and was pretty pleased. I took it outdoors and sprayed workable fixative on it. I almost always do that. I've never had problems with it before. But this time...horror of horrors, my dark purple shadows morphed into something more like neon fuschia. Not so good. I used much more Verithin Prismas on this particular work than I normally do and perhaps that accounts for the color shift this time. So, back to the drawing board - literally. I busily attacked the purple with a marine green and think I might have counteracted the effects. I had been so careful to maintain my lights - which is always a challenge for me - and was annoyed that I had to get some subtle gradations darker when the additional coats of pencil were applied. Oh, well. I learn something everytime. I had been working on this one as a submission for the CPSA Int'l exhibit. I didn't enter at all last year and regret that decision. I hope to complete another one and will start on it today. I am giving pastelboard and Neocolors II wax crayons a try with my next one. I will try to post the work in progress - if I don't forget.
Hope to be back here soon!
All the best,
