I completed this quite quickly. I started off using the same sort of shading technique I use on my surreal drawings, then half way through tried to speed things up a bit with a more dynamic shading type!
Well it's a little known fact, but that town that begins with B, where you live has a honeycomb of caves and caverns underneath and yes some of them do lead to an inner world where dinosaurs co-exist with advanced beings! There are also several time/space continuums which allow you to go back in time 10s of thousands of years, and a vortex which links to a planet in another galaxy!
omgs! I need a map to that trapdoor then! I could co-exist... I'm not an advanced being but given the little known fact that dinosaurs are very fond of south indian cooking, maybe i could get some shift work in the kitchen? ^_^
