On the West Highland Way? The weather has been really nice for the last week and it's a place I'm quite fond of.
First 3 shots look a bit muddy, so I'd try setting a white and black point. There's also a fair bit of haze around at this time of year so a clarity and contrast boost on the hills can bring them out a bit more, lightroom has the dehaze slider which can be very useful in small doses. 4 th looks a bit underexposed and I'd raise the shadows in the 5th to bring back a bit of detail in the bridge.
