Tiger looks really good. Obviously you are not finished but be sure to get rid of those white lines on the broken zim....and definately paint that gun tube. Never leave anything bare metal...not only very unhelathy for camo but rust/corrosion would drive the crew up the wall. The 505th in Russia painted the first section yellow with the tank number on it, so there's a bit for variety a disregard for camo, but absolutely no bare metal.
