You did a great job on that river. Read your blog, and I found it very illuminating on the process of making it.
Cheers. I actually suffered a bit of a set-back while writing that post, since it took about six weeks or more from start to finish and I lost my phone with a lot of the WIP shots on it about half-way through. I usually try and detail which products I'm using, what things worked and what things didn't, as much for my own sake as anyone else's, so I can remember how to replicate projects later on down the track!
