I am a watercolour artist, a musician and member of The Royal Society of Marine Artists
I was watercolouring recently in the Oxmarket Contemporary in Chichester. Finished this one. I also had my sketchbooks in the gallery, great to show them, then sharing creative directions and swapping techniques with other artists. #oxmarketcontemporary #watercolour #livepainting

Bosham Calm. I was painting this plein air in watercolour but I couldn’t get the light. This is 30 minutes in with Golden Open acrylic and I love it. The letterbox canvas size just makes me think of my moleskine. #acrylic #bosham #royalsocietyofmarineartists #goldenhour
