Thanks for sharing, Rob, great work.
As you noted that the cammo colours are wrong, may I assume that you went for the grey shades instead of the blue ones?
Then, I don't know if this is the final product, but there are a few things about your deck colours that strike me odd. First, you have round areas around the 10.5 AA guns left in a wooden colour. Why is that? I mean, the blue is wrong there too, as is the wood, but why leaving these circles around the gun mounts?
The colour of the wooden crated panels on the open bridge are said to have been more brown in colour, maybe they were stained.
The wooden slatted panels of the foretop gallery could have been a different colour too, not the same as the main deck teak 'colour' ... there may have been other decks or platforms with those slatted panels, i.e. searchlight and/or AA gun platforms - but I don't know for sure ...
However, this is great work and I wish I could do things like that!
Happy 3D-rendering ~ Olaf!
EDIT: As someone noted before: It should be "Schlachtschiff" Scharnhorst, not the plural "Schlachtschiffe" ...
