Texturing Sci Fi Environment

So I've been trying to texture my final project for my Hard Surface Modeling class last semester and use Marmoset Toolbag for the rendering. For some reason my normal map file isn't working, but for now this is my first pass at the textures since I only wanted to get some base colors down on the mesh.

I'm trying to mimic the visual style of Borderlands 2 in this environment, so I'll try to get some critique from some of my old class mates from the U on our Facebook group.

Here is the render:

I plan to take some time doing this crate, so that once I have the look I want I can then move on to the other pieces in the environment without having to stumble so much looking to see what works and what doesn't.

That's all for now, thanks for reading!
