A few days ago Jacqueline @jacqbb asked how I managed the "water ripple". (Green pic). There I used something similar, like in this picture. But as overlay. Here is as original and basic layer. It is "just" curvy vase (sideways) and I let the light do the ripple and faking the water. (Btw it is the same vase (cheap swedish furniture house vase), I used in the pi two days ago. And the setting sun, is just a lamp behind some orange papyrus, the figurehead a tiny tinker bead and the boat is paper too. Of course. The whole scene is probably 5cm x 5 cm.
You are so creative to be able to see these things ahead of your photograph. I appreciate that you are willing to share your process with us. Thank you Mona.
