If you have not done much PPing, personally, I wouldn't start with a Judy Niemeyer pattern.
Not saying that you couldn't, but for me I would sooner work on something I knew I could handle before I went for a challenge such as that!
I learned PPing doing the FWS blocks.
When I started, I figured, that if it was not for me, all would not be lost as I could have a bunch of mini quilts or pot holders, using the single blocks. Or could put a few together for a table topper or runner. A few more for a baby quilt, more for a throw, and so on! Yes, I got to the end and even made some extras. I discovered that I loved PPing, but at the start? Nope! I'm glad I gave it a fair chance!
Other good starters along with the FWS might be the PC or DJ quilt or other similar ones.
That way you can do individual blocks as you build your PPing skills and confidence.
You'll then know if a JN is for you!
