Here are some of my book cover illustrations. Some are also my design. From top to bottom:
Tyrannosaurus rex vs. Triceratops horridus - Vijesti Hrvatskog geološkog društva ( Croatian geological survey's news magazine)
A pliosaur Liopleurodon on the cover of my book that hasn't been realised (yet), but the illustration was published in a National Geographic magazine.
"Power bites", a dinosaur poster published in 1993 by Scholastic.
"The Pirates": a self-promotional experimental cover.
