Hi Jeff,
Delightful photograph. It could be larger! So many people hardly moves in 8 seconds! I like slow exposures since they get rid of a lot of unimportant transient detail and in addition you have achieved a painterly look which is intriguing. Seems to be a lot of green in the light to nice effect. I do miss the rest of the grand scene. The window top and roof are missing! Do you have more so you can stitch. Again I long for excess coverage. I always try to take adjacent shots generously at the same settings. It takes a few secs and can make a picture exceptional.
In any case you have a fine subject and technic. Can you do more? This scene calls for a grand view. It's very worthwhile.

BTW: I thought, hmm this was taken with the Panasonic Lumix DMC FZ-303 and lens filters. So I asked myself, why 3 filters? ND so you can use a slow shutter speed? Then I realized you are listing your gear, LOL! That list is better in your profile. I'd still like to know which camera you used!
