When you change the colour of a texture you change more than just the colour, you change the effect of certain light spectrums on it, you bring details that sometimes are often left wihtout emphasis, or conversey you hide details that are normally present.
Looking at it already you can see that it appears brighter. You make more of the finer points of it, its not pleasant to the eye. Compounding the issue is that you haven't matched the texture mapping style used on previous Liberty ships. It doesn't integrate seamlessly.
The texture scaling makes it feel like it should be fighter sized, especially the ventral engine pod. It needs a complete overhaul to be honest.
