Abstract Exercise #3 - Variation 1

Exercise #3 from Rolina van Vliet's fabulous book. This one is rectangles with dark spaces in between. I love the colours of it (and the photograph doesn't do it justice - the original had a blue cast, but this one looks a bit too yellow). I might paint a larger version of it (it's about 40x20cm). I have a large canvas that's begging me to use it.
