I like this, I think with out the people it would be distinctly average, but with them you get the scale of the landscape you start to wonder how far they have come, I like the foreground as it gives a little idea of where they've already been but also the view point makes you wonder how much further they are going as there is very little by way of civilisation except a small group of buildings in that far distance, personally I'd loose about half the sky if not a little more than half of it keeping to width so going to a more panoramic crop as go be honest the sky is boring there is very little going on in it so your not doing to miss it and I thing it would give you a more pleasing composition
