I take my hat off to those that can build something as stunning as that, starting from a piece of styrene sheet.
It gives me something to strive towards, and keeps the dreams alive.
But for most of us, it's not the skill level that holds us back , it's time.
At the moment I have a C119 Boxcar that has to have the entire internals scratchbuilt, from the airframe through to the rollers on the cargo floor, but all this takes time that I do not have in abundance.
One scratchbuilt model that really blows me away is Ben Guenthers Vought Vindicator, in Great Scale Modeling.
The frame he made from brass really makes me cringe trying to imagine getting the scaling correct.
And in 1/72 scale.
