I love that new stream and your brick wall is just first class....which is a result of the time and effort you put in to cutting it into shape etc. I really does look awesome. What I particularly love is the height you've been able to achieve on the wall (something I wont be able to do).
The colour of the stream is perfect too (I should know as I've paddled in it!! The rocks around the stream are also very red and in places stain the water in the same way - just as an fyi.
What did you use for the water in the end (apologies if i've already asked this)?
