Ryszard, Just an outstanding build, and an equally impressive presentation.
Your build could have been OOB or super detailed, but it really doesn't matter in the manner that you have presented your LT-6. A simple, yet highly effective vignette setting. The model looks like a 1:1 real aircraft, especially with the natural lighting, which is what this hobby is all about.
The near perfect NMF looks basically monotone with the exception of the engine cowl, yet is subtly weathered so that one gets the impression that's it's a depiction of an aircraft that has seen time in the air, yet well maintained.
