Stage 5; I decided that in order to paint the reflection of the penguin in the wet sand I'll need to paint the penguin first so that I know what the colours of the reflection should be. I've started on the penguin - the beak and head are nearly done and I've added a bit more white to the sunlit underparts. I've also slightly altered the angle of shadow cast by the wing over the flank as I realise that the sun is low in the sky so the shadow should be a bit more horiziontal.
