'Walkers near Mullion Cove' is wonderful. Excellent use of the panoramic format here. The tonality and isolation of the walkers makes them a strong subject, but there's plenty to keep the eye interested in the rest of the frame. The grassy hill could have been boring in monochrome without the flowers, but they add enough tonal variety to keep that from happening. The BW conversion is nice, you've got a full range of tones but the contrast doesn't looked forced.
'Farm gate at sunset' looks overprocessed to me. I don't knokw if this is a case of HDR tonemapping gone bad or just oversharpening, but it has the crunchy, digital look I don't like. There are haloes on high-contrast edges and the grass in the foreground is way oversharpened IMHO.
