About Mariana

Her work is fuelled by humour, cuteness, and a love for vibrant colours. Outside of her studio, Mariana has a soft spot for cats and foxes, loves getting lost in piles of books, and never says no to a delicious sweet treat.

📙 Illustration Styles

Mariana’s style is simple and cheerful, characterised by expressive characters, rich textures, and vibrant palettes. This aesthetic is a perfect fit for early reader formats, such as board books and preschool picture books.

To receive accurate details on pricing and timelines, clients are advised to specify their preferred illustration style in their quote request.

📙 The Process

Creating a book is a journey! Her process is divided into three key stages:

Sketching: This is the foundation where concepts and layouts take shape. At this stage, the focus is on the visual direction and storytelling before moving on to colour.

Colouring & Final Art: Once the sketches are approved, she brings them to life with colour, lighting, shadows, and those all-important finishing touches.

Cover & Lettering: After the interior artwork is complete, she designs the cover and creates custom title lettering. Once approved, all files are finalised and delivered in high resolution.

📌 Important Notes

Timeline & Pricing: Clients are advised that production time and fees may vary depending on the chosen style and level of detail required for their project.

Final Proofing: The author is responsible for a final, careful review of all materials before files are sent to print. To ensure everything is perfect and avoid printing errors, hiring a professional proofreader is recommended if needed. Please note that the illustrator is not responsible for final text or layout proofing.

Services: Clients are advised that Mariana specialises in static illustration and does not provide animation services.
