I suppose its a bit of a cliche for an artist to say they are inspired by nature, I will just say I am heavily influenced by it. Its affects it has on peoples physical and mental well being is only just been scientifically understood but I am sure everyone who has spent a day outside instantly feels the benefits.
Watercolours lend themselves so well to nature as like nature they can have a chaotic nature. If you are looking for precision don't paint a watercolour landscape. If you are looking for swirling skies and organic trees then do. Pick yours today.
