That is just wrong that you got all those 3,2 and 2-1's. I thought that this was really good, after seeing all the very busy patterns this one was a relief on the eyes. Well done!
Really interesting shot. I dont prefer your crop that you cut off the top in a pattern challenge. I think I would've like to see it centered in the left third of the shot. Still, very nice and sharp.
This is just me, but I would have liked to see the entire circle (chrome one), not just a portion. The concentric circles are a pattern as well as the "blades."
