The Italian Chapel shot is certainly a new slant on a well-known location, but I'm not so sure about the amount of plantlife in the foreground hiding part of the building. B&W is an interesting choice, but I think the colours are a part of the chapel. The flatness of the Fields shot gives a decent impression of what Orkney is like, but you've paired it well with the cliff shot below for contrast. A head for heights would have maybe got you a bit closer to the edge, although perhaps you could crop some of the grass out at the bottom to give more emphasis to the monument? I've been to orkney on business, but never managed the holiday there that I've promised myself.
