first of all congrats on the shot and the beautiful scenary you got in the frame.
There are no technique mistakes to be pointed out as the framing follows the rules thirds/planes and the focusing depth is good in takign all of the details in the scenario. The only minor technical detail I would point out is that you could have tried to leave a bit more out of focus the very first part of the first plane and gain a tiny bit more of "real" definition" in the background.
lovely also the blending between the ground/mountains and their reflection in the pond.
Keep up the good work,
