What size I will be if I'll have 100, 120 and 140 cc round implants moderate projection? (Photo)

It is not unusual for models, or others in the public eye to want very conservative and natural looking breast implants. The key is not just the correct size in terms of cc's bit the correct shape of implant, placed in a way so that the implants aren't too high, too far apart or placed in any way that makes the breasts look "done" . Overly large breast implants almost always look fake. But small implants can look fake too without proper placement. Biodimensional planning is essential for selecting the proper size and shape of implants. 

If you are concerned about too much upper pole fullness, you might consider a shaped implant such as the Sientra or Allergan 141's rather than a round implant. From your photos it appears as though your right nipple is slightly lower than the left and this asymmetry will persist after surgery.
