Really like the composition here. Doesn't look to be in sharp focus too me. I'm sure you have some wind to deal with in the mountains. These grow where i live in Upstate New York.
The DOF looks a little limited a consequence my eyes are constantly roaming around the flower heads. Cameras with high MP sensors areunforgiving, they require particular attention to detail, I think your chances of success handholding at f3.5 are going to be very limited. I think you would have needed at least f8 at this magnification. Depending upon the wind velocity 1/800 sec should've been ok hand holding.
