Plusses - the tyre tread is very nicely done, as are the canvas weather covers. I like the optional metal / leather panniers too.
Minuses - I know it's already been debated to death, but the solid spokes look like they belong on a smaller model. The engine detail seems a bit 'soft' too. Are the horizontal cylinders separate parts?
I suspect most of us are waiting to see how the crew turns out. That's what will really sell this kit.
