This is what I have done so far on the second in the series. I don't like the triangular block on the left, because it's the only triangle in the piece. It will probably end up in the parts drawer. The bottom left one looks pretty blah in the photo but has more contrast in real life. This is the first arrangement and will change a lot I'm sure. I'll probably make some more blocks too. I am happy with the subdued (for me) colors so far.
