Technique and Process

This small project was a pleasure to work on. The deadline was very tight (one month) and my task was to create a series of 15 illustrations and other small decorations illustrations, that would be beautiful to the eye but also educative. Because I had to work fast without compromising on quality I chose to combine pencil and digital colouring, this time choosing to enhance the sketchy look of the lines and make the pencil lines stand out more, for a playful effect.

Where to buy

The book will be made available throughout a network of private clinics in Romania.
