A couple more paintings, of the 'Catherdral built by nature.' i thought the colours worked well in the top image, although it seems a little cramped and not very spacious in this one. I might make the centre tunnel bigger, and more detailed.
This image is a bit rougher and id found that the rock shapes i was drawing looked a little too big, although i thought the water appeared to guide the eye into the distance in this one, which i thought worked quite well. So i may come back to this one.
