I also changed paints with this and the Marder, the Mig Panzer colours don't really do what they say on the tin, they are mixed for airbrushes and therefore too thin for use with a brush to get the best effects. The two rust colours have been excellent however the Vallejo Panzer Aces are more suitable for brushwork, having said that it was too late to check if they did German camo colours, I am sure they do but a base of Dark Sand, Russian Uniform green and Red Leather have worked just fine.
I have not put stowage on the Panther and don't intend to, I think I have only ever seen one with a lot of stuff on the back and I am unsure of that, the problem would be the engine grills on the rear deck, you simply cannot clog them up in case the engine overheats, at least that is my guess. I suspect it is the same on the Tiger, but then again I can only put water and petrol in my car, so I could be way off.
Nothing exciting for the future, apart from a Churchill at some point, I am going to get some Kubelwagens, a command SdKfz 250 and some jeeps for the British. I did fancy getting a Horch and a Dorchester but the prices are bugging me, not that the others are much cheaper. I will complete the last German squad next week and then do a couple of other small projects which have been left on the side before getting back to WWII.
I have just noticed I haven't painted the tools, see what I mean about patience and the lack of it.
