Reminds me of the recoloured issue of G2 Transformers Dreadwing and Smokescreen.
What I want vs what I got. The burgundy-ish tone on the right is too dark for what I had in mind, so it's back to bare metal for the frame, almost anyway...

Fuel tank is coming along quite nicely.
So tired. Any more sanding and I'll have no fingerprints soon.
