6 Weeks Post Op Breast Augmentation. Can This Be Fixed? (photo)

Photos are of NO help! Best to be seen IN PERSON by your surgeon or second opinions!!! And YES very early to be considering revision. 

It is a little early to consider a revision but looking at your photos it appears that you are very thin.  The more soft tissue that covers the implant the more natural the appearance.  Your result may be about the best you  are going to be able to achieve with implants alone.  If you what some improvement it is possible that you need to consider a breast lift.  Hard to know without an examination.
