This is the second order from previous customer.

My method just for an interest:
1. Go to the sea shore to gather rocks not to small and not too big! Might take some time.
2. Take home and was thoroughly, let dry, go over them with a sandpaper.
3. Paint with Gesso, when dry, another coat with white acrylic paint.
4. Draw up the shape of fish.
5. Start painting.
I always start with acrylic with three coats at least, there is a lot of mixing for each tone or color. This time I am finishing with a Gouache which is quite enjoyable to handle because it does not dry as fast.
