Fantastic photo. My camera club did Slow Shudder this month and my results, I'm sad to say, weren't even close to what you achieved. I now know how hard it is!
It is pretty difficult, I've been trying these for over a decade and still can't nail them down. Read the light. If it's cloudy you can get away without using an ND filter during the day. If it's sunny, you're going to need something to block out light and that's where an ND filter comes in handy. I have a 3x, 6x, and a 10x ND filters and I would say that I use the 3x most often. Just my two cents.
