FIRST visit to this thread, got more and more impressed as I went through it. Gave up trying to think of what to say, think MAYO said what I shoulda said . . . .
Congratulations! You really underwent a significant transformation. All that hard work really paid off. Time to set your next set of goals to stay focused.
"Size wise" I think you have plenty. I'd work on Conditioning as Glute/Ham tie-ins are gonna be your stubborn spot (for many women). Your back, delts and arm looks GREAT. Be proud of your transformation. I'm also in the Masters +45 class and it's damn hard to get dry and lean at our age. Bravo!
