When you are capable of travelling in excess of 500 km/hr, you don't have many things left to race against.
I have made one render each week for the past 3 weeks (I am inclined to make it into a habit) and I have impressed myself with what I am able to make ... I had so much fun making these, I focused on texturing, lighting, rendering and post processing. While I still love modelling everything myself it can very easily burn me out and makes me less and less interested in the project hence I decided to focus on everything but modelling.
