Just took a look - everything looks great, very nice work! I'm loving the pebble beaches.
My only feedback is that I think the grass mix could be improved a bit. Rather than mixing the meadow fescue, heather, and other grasses randomly, I'd use heather predominantly in some areas (like around the cliffs), the fescue predominantly in some other areas, and the other grasses predominantly in the remaining areas. That is, create different vegetation zones for more visual interest. Or at the very least clump some of the grasses more so it seems less noisy.
