This is the second Wooble I've ever done, and I had so much fun with it. I found the second time to be much easier as I was already familiar with the different stitches. I felt more confident, and I think my technique looks a lot better as a result.
The design of The Joker is just so cute! His little bowtie is my favorite part! I decided to do the hair a bit differently than the tutorial. Normally, you're supposed to sew the curl of Joker's hair down to make a pompadour shape, but I really liked the curl, so I kept it free.
The tutorial videos were also great and super detailed! I never hit a point where I felt stuck or confused.
I would definitely recommend this piece, even to beginners. I'd say Joker was technically a bit more complex than Batman, so if you are a complete beginner deciding between the two, I'd say try Batman first and then advance to Joker.
