It looks really good, and I'm sure you're wanting to wear it tonight, but here's some unsolicited advice I recently learned from a master seamstress. When making a lined garment, one should hang the garment (as you've done) and leave it alone for a week, to let the shell and lining "relax" (stretch under their own weight) before sewing them together. Since your cape is made of different weights of fabric, it might be worthwhile to let it rest for a few days, just to see what happens.
