The links on your post didn't seem to work for me but I watched them under Megalithic Poems which did work.
Your films are very interesting and I enjoyed the Danebury Hillfort one a lot. I watched all three of the Carbon Dating films and would need to watch them again before making a constructive comment.
First impression was they are a creative and original stream of consciousness - could almost be an entry for the Turner Prize.
PS:
