You took that bit of inspiration from Van Gogh and did him proud!

What I like about this painting is the way you indicate so much with such little things... the lighthouse light being like a little sun for the night time, and the gold of its light illuminating both the stiller water shielded somewhat by the cliff, and the great waves tossing white and high and breaking more than halfway up the side of that cliff. The waves and the sky itself ... the light spinning counter-clockwise through the sky and then rolling like a wave of energy holding down the energy of the tossing sea. Details, details ... the second of the two waves is actually a little higher than the base of the lighthouse, but it has already broken and is falling ... there is no way the sky is going to let its night sun be extinguished...

Other details I loved ... the waves hitting the shore like so many sensitive fingers, rock climbing their way up and down... the little purple fish swimming in the stiller water... the golden light catching the seaweed on the rocks ... the little stream of water running from under the lighthouse suggesting that not too long before, some rogue wave DID reach the base of the lighthouse... but the wave is gone, and the lighthouse and its light remains, undisturbed.

I don't think you should add anything. There is so much of a visual feast already! Thank you for sharing!
