Is my butt is supposed to look like this after butt implants or it will look more natural? (Photo)

Hello, I just recently had buttock implants on the 07/13/2018. I love the size and projection from the sides and front however I'm not so sure about how I look from the back, it looks too boxy and unnatural and I was wondering if that's because of swelling and if they will look better later on and if they will drop. Also I was wondering is some of this size swelling? I'm in love with the size and I don't want to loose any of it. Implants are motiva anatomic body contour implants 555 cc. Thanks.
