I started with the sketch. In my sketch book which I then transferred onto Watercolour paper. I do this because, if I make mistakes and rub out my pencil lines etc this can damage the good paper. So I do all my sketching and mistakes on my sketch book first. Then trace the finished sketch and transfer it to the 140lb hotpress watercolour paper. I then Sat at my desk put on some inspiring music(without words as I have a tendency to sing otherwise lol)
This is what the painting looked like after the first hour of painting.
