For some reason I am firmly convinced that Nargothrond must have been powered by a goodly number of waterwheels.
Here is a random Noldo wandering past one of them. I did this with my new Inktense pencils, which I recommend if you like watercolour pencils, they are like those but much more vivid. The falling water was overpainted in acrylics, and I think looks better in the physical version than in my photo here, but that's life.
The New Year began yesterday with a truly horrible cold wet and rainy day. I determinedly went out for a dog walk in Calstock with my mother anyway, and duly fell over in the mud and got very damp and filthy (better her than me though, I am young enough to bounce!). I wish we'd left it till today now, the skies today are a clear blue and everything is green and gold again.
