You did not show your before photos, but your second looks good. Measurements are needed to be sure, but the implant on the higher side could be exchanged for something a little smaller. Otherwise, I would suggest keeping what you have. Every surgery has risks, and each surgery adds more...
The implants could be lowered to settle down in the breasts, but you may find that you are sagging. Measurements are needed to see if a lift is needed, but I suspect you will need a lift.
I would discuss this with your surgeon. What can be done depends upon what your surgeon is defining as an internal bra. There are different options, but some work only under the muscle.
