I have tried to keep it relatively clean and crisp to match the rest of my army. I'm not however 100% happy with the smoke and heat marks around the exhausts so will be adding a little blackening to that with powder (thanks for the advice Shane).
All comments, criticisms, advise and what ever else you can think of most definitely very welcome, so do your worst =P
Sorry for the quality of the images, still running on my iPhone as I don't have a good camera.
