Grand Marais Lighthouse Timelapse

A timelapse I shot of the Grand Marais Lighthouse in Grand Marias Minnesota on 12/19/2020. The gear I used was a Fujifilm X-T2 with a 50-140mm f/2.8 lens.
EXIF Data:
Focal Length: 65mm
Aperture: f/7.1
Shutter Speed: 1/40 sec - 1/10 Sec
ISO: 200 - 500
Interval: 4 sec.
I wish I would have thrown a 3 stop ND filter on to get my shutter speed down to 2 seconds or so. Another tip is to make sure your sensor is clean before you start shooting a timelapse. It can be quite difficult to remove in post, I think I did a decent job but it is not perfect.
I would love to know your thoughts on the timelapse and if you have any advice for future timelapses as I am still trying to perfect my skills.
