That is great, one of the things I noticed is German didn't use the new heat shrink tool, he should have had it in his version (11.5) when he is trying to form his boiler stack and smoke stacks around the cylindrical boiler, that tool is exactly what you need to get good quick results, he did it manually which is OK, but it would have saved him several minutes because it is a simple click and drag operation.
So, the newer version do have some great new tools to use to get that model looking good, good luck and have some fun!
