Thankyou Q / C that is painted on some very special watercolour paper HOT pressed , which means there is next to no texture to the paper as opposed to COLD pressed and then you move into the ROUGH papers .

Its horses for courses TBH it looks a lot better in the real that one than on here as you can see the grain in the paper

It has also been built up by a process of transparent washes of paint to give it a see through body ,, glad you enjoyed it
