Not happy with shape/size after TT. Are ab muscles at the tightest now or would they still need more strengthening? (Photos)

I had a tummy tuck, with muscle plication + lipo 12 weeks ago.While there is a great improvement overall, I think I had greater expectations of a flatter tummy. At times I still look slightly pregnant. I have always been an apple shape, never carried much weight, but when I did it went to my tummy, lending me to look pregnant even when not. I thought I would shake this look after the tummy tuck but not really. Does this look right, or can it be fixed? Could my muscles need extra strengthening?
