Hey, I know you've been doing this for a lot longer than me, but why not go with contrasting shades of orange on that bike instead of black on orange?
Actually my skills evolve with each build, in the past I have assembled with the parts as they arrive with intent of a ratty look.
The black on the tank was driven by the black and white fenders that arrived. I understand your concept and it would look really nice.
With this build I got to experience the failure of rattle can paint and gas. I have striped the tank. It is not yet painted.
This build has is the driving force behind my airbrush purchase. Why? Because I will now be painting tanks with model air plane paint. And the act of owning an air brush will be the cause of more detailed and painted builds in the future.
Finishing touches on the OP remain like lighting, but my main focus is now on the Puma Twin engine project.
