Pull My Strings - Completed!

I just completed my first teaser puzzle, Pull My Strings. I have had this puzzle out for at least 6 months. Once or twice a month I would spend a few minutes as life just seems so busy lately. And until today I had the outline, the Chinese dragons and a variety of 2-3 piece groupings together. This afternoon I finally had a little free time and I thought some time with a puzzle would be nice. Once a couple groups got in place everything just fell in. Its a beautiful puzzle, many thanks to Dee Rogers for the design and to 'BM' for the great job in cutting. There were some nice little tricks in there.

My only other uncompleted puzzle is the trick puzzle Metamorphosis which was driving me crazy before I started Pull My Strings. Any hints for that one?
