Still-Life with Tuft of Marine Plants, Shells and Corals

Lightly sketch the basic shapes and arrangement of the objects on the canvas.

Block in the background with a dark, neutral color.

Establish the main light source and begin to define the shadows and highlights on the objects.

Start with the largest shapes, like the marine plants and large shells, gradually working towards the smaller details.

Mix and apply the base colors for each object, paying attention to the local color and how it is affected by light.

Build up layers of paint to create depth and dimension, blending carefully to achieve smooth transitions.

Add details such as the textures of the shells and the delicate branches of the coral.

Refine the highlights and shadows to create a sense of realism and finish with any final adjustments.
