“I Had a Double Mastectomy ,expanders Now 800cc Silicone Implant”

I have always had big Boobs and loved my cleavage .I was so sad when i found out i had cancer. Praise God im cancer free now ! But i just had my silicone implants High profile 800cc put in on 8/12/10 , But my breast dont have much cleavage there is no real round look to my so called DD's its looks like 2 big mounds .will they get more define and look more real.is the swelling all around the implants keeping the boobs from looking like boobs.I showed the doctor what i was wanting to look like and he never said that he couldn't get them to even look close to what i was wanting to look like.what should i do.

Just for some info on my body shape ...I am 5' 5'' and 170 and losing some weight finally and planing on getting lipo and a tummy tuck.most of my fat is around my waist and back ,shoulders and arms.could this be the problem with how my new boobs are looking.
