I rather like it as it is wondering how big it will be or is it just the 6 blocks, also what if you reverse some of the blocks using the background fabric as the pinwheels no not sure that would work but just a thought
I was just going to suggest making one or more (depending on how big it will be) in the reverse colourway but see Margaret has beaten me to it! I actually rather like it how it is though, it's very restful on the eye and has a lovely flow to it, but it depends what you are going for I guess!!
One of the things I came away with from her talk at Guild was the use of "dull and bright". You have dull and medium going on there,,,maybe stick in a few dull and bright? I can see how D&B popped in your picture of your Rail Fence Quilt Along.
Ok, here's my two cents. I know nothing about the construction, but how about just one spoke in one block in orange? Or, since odd numbers are best, maybe at most three. Two orange and a yellow, say. Have fun!
