A maze brain for Gardening Australia magazine

Hello!  Please excuse this bad photo of this month's Gardening Australia magazine.  I sneakily took it at Mag Nation.  Frustratingly,  the subscription hasn't arrived yet.

This is actually my favourite illustration so far.  I am really pleased with how the 'brain maze' turned out.  It was painted using acrylic on wood, separately to the little thinking man below.

They were both cut out in Photoshop and then he was superimposed.

Here is the first version of the sketch, with the maze part kind of in reverse.  It didn't work as well as the final version.  In both cases I traced over an actual diagram of a human brain.
