An illustration from "In the Company of Light" / "U društvu svjetla", a picture book I wrote and illustrated, published by Sipar.
Here, the little photon of light has reached the end of the influence of our Sun in the Solar system and is ready to take the leap beyond, into empty space and the unknown.

You can order the book (in croatian) here:
