Its hard to see what you are describing by the photos your provided. Its possible that your implant was placed too superficially. Sub muscular placement may be a better option. The only issue with sub muscular placement is that it doesn't provide you with the projection most people are looking for.

Visible buttock implants
Unfortunately the photos provided are insufficient to determine the possible problem. Only an in person physical exam will be able to clarify your problem and then hopefully suggest a possible solution. Glad to help.
Dear miss, Thanks for submitting your pictures, however it is not clear from them what is bothering you. You have to submit front and side view pictures standing and possibly when you bend over. The reason for the implants being noticed, could be capsule contracture or using round implants which are not anatomical. Since you want big and natural butt, your only option is to consult with a surgeon who uses technique and implants similar to my approach - sub fascia placement of ultra soft oval round silicone implants. This approach allows for big implants (my biggest is 660 cc , but bigger can be used on the right patient), which create nice 'S' curve (shelf) and nicely round hips' curves. Best of luck, Dr Widder
