Great idea for this challenge. I like the view of the old details of the vehicle. I think it could have even been better by bringing out more of the colors and details (I think this would be a great chance to use Topaz products).
Be prepared for criticism on this picture for the blurry wheel and clutch. But none here as I distinctly got the feeling of sitting on a tractor. I'd say more steering wheel! Take a picture from typical POV.
