May I start by saying what a beautiful capture. The inclusion of the 3 counrties mentioned, has really been emphasised by the 12mm focal length and the panoramic display. You have really done well to compliment the richness of the european countryside, and deep azure sky. The real grasping focal point of the image are the centralised clouds with the deep contrast which really epitamizes how far back they reach. You have played well with the rule of thirds, although I would have liked to see maybe a little more of the foreground, or maybe somthing to lead into the photo, perhpas a row of trees, a path in the floor, or some foot prints, but as a fellow photographer I realise that foreground interest isn't always neccassary and some things can limit what is included. But thats just a personal view and may not be to everyones tastes. All I can say is congradulations on the capture, and i'm jealous that you got to be here, and i'm in the UK enjoying some lashings of rain. All the best. Richie.
