Wow! Week 4 this is great fun and I am learning so much. Week 4 challenge of white pumpkins is all in waterbased oils. I used only 2 colors plus white, but unfortunately the painting posted does not show much of the yellow, but I did use it in the purples and whites to tone down the purples. One thing I really want to improve on is to do a painting in 1 day(a couple of hours) instead of it taking me 2 or 3 days to complete just one. That is my next challenge for myself, hope I can do it. Anyway I want anyone who is reading these posts to know that Karin Jurick is a fantastically gifted and giving artist. I pray God bless her richly with all His goodness. Thank you Karin.
