Digital illustrations for book series

Joaquin is about to finish writing the second book on his “Save Earth Mission” series. We’re talking about literary works of about 15 chapters 80-100 pages each, which he has authored and illustrated completely on his own. While his writing has improved greatly from the first to the second book (regularly composing sentences as grammatically complex as the ones found in some of the —much higher than his grade— books we’re currently reading), this post is all about the illustrations, which of course I adore. Here are some of my favorites.
