Looks like fun! X4 for Pearly. Take your time and go slow. The last one I did looked very similar to yours, and I just pulled one tip in a bit to line up the string and then set in 3" of reflex. Tillered her out slow and she's one of the smoothest self bows I've made to date. The only other thing I'd suggest is when she's close to where you want, maybe toast the belly a bit to help hold in some reflex.
Back her with a snake skin, too. She'll look great!
