Problem #1 Your hair did not completely dry.
For those who do braidouts on damp or wet hair, drying completely (like with rollersets) is essential for getting the look right. But there are times we head to bed knowing our hair is gonna be too cute in the morning only to get damp, limp looking hair! If you get up early enough to note the braids are still wet, sit under your hooded dryer for 15 minutes or so to help it dry and set. This is never me, I hardly have even two minutes to spare in the mornings let alone 15! Another option is to use a diffuser, which is made to dry curly hair. It can help your hair to dry without causing frizz and even make your braidout look more natural, especially if you ARE natural.
Problem #2 The waves/curls just don’t look right.
Try an updo. Clip it up, curl it up, pin it up. Textured hair makes some of the cutest updos in my opinion! Here are a few videos of different braidout updo styles I have done, one especially for the braid/twist out that didn’t turn out right:
