Little story behind this...Over on Twitter I usually partake in a weekly illustration challenge, and the result of this week's prompt was a 'Spectrum Pursuit Vehicle', more commonly known as an SPV, from the 1967 series 'Captain Scarlet and the Mysterons'. Think of a road legal tank in metallic blue with a concealed canon and tyres instead of caterpillar tracks and you're pretty much there!I always tend to post a small preview of the pencil sketch, this is where unfortunately thought I was going to draw Vinyl in a tank. Well, I couldn't exactlydraw that now, could I!MLP:FiM owned by Hasbro.
