Way to have your camera ready at just the right moment. It’s evident that you were thinking about “composition” when you snapped this; all to often I zoom in on the spontaneous subject, snap a million shots and forget about how those subjects actually play a role in the surrounding scene.
There is an imbalance of heavy elements on the right side of the picture: the sun, the geese flying over, the open barn window. Even though there are two gabled windows and cupolas to balance each other out, they don’t help to balance out the other elements. I would have tried either going vertical, zoomed in to only include the top of the barn, or snapped the shot when the birds were further to the left, directly in between the cupolas.
The HDR effect was performed well. Hard to tell how it was done. However, the sky is just too dark (or perhaps the barn is too light) to look natural enough for my liking.
