Yah, I thought the skin was a little weird on this one. I lightened it up though, I should post it.
it would be kind of hard to do more detail on the Canopus though, it is quite high poly already. What do you think is exactly wrong with it? On the colours, I used multiple pictures for both the last two, a lot, mostly of models and a few drawings (as colour photography was not around at the time). I do agree the HMS Warspite looked a little bland, but with the lighter colours she looks better.
Edit: Look to the first post for the lighter skin.
