I am a bit partial to loons of all varieties, so always enjoy seeing them. I also think pan blurs can be quite effective, but for me personally, I prefer them when the head at least is sharp. Moving/blurry wings, water and background all can work, but I prefer the head to be sharp.
I like the diagonal line of the reflection in the frame.
Hi Geoffrey, I like your choice of pano crop, and the take off pose. Glad that you managed to get a reflection, even though not the clearest. I agree with the above of having at least the head sharp.
