I accept commissions for animal portraits, landscapes and seascapes using various mediums including oil and gouache.

My commissioned paintings make great gifts for loved ones or a beautiful addition to your own home. So if you're looking for a truly unique piece of art, browse our commission pages and let us bring your artistic vision to life!

Animal Portraits

My animal portraits are normally produced in gouache on Daler board, to produce the finest detail possible. I like to paint on a black ground to isolate the subject from the surroundings, making it really stand out. Subjects can include dogs, cats, horses and other animals.

The painting will be overlaid by a high quality matte custom made for the correct proportions, ready for framing in a standard frame size. To commission a portrait please click here.


Landscapes and seascapes are produced in oil and can be painted on stretched canvas or board. With an oil painting, you'll have a timeless piece of art that will be cherished for generations to come.

Certificate of Authenticity

To ensure the value and authenticity of your investment, all my original paintings are supplied with a unique signed certificate of authenticity.

This certificate serves as a proof of the origin and authorship of the artwork, confirming that it is a genuine and original Sian Williams work of art. It includes important details such as the title and date of the artwork, and information about the materials used in its creation.

By owning a signed certificate of authenticity, you can be confident that your artwork is an original and authentic creation, and that its value will only increase over time.
