What would *you* recommend to spiff things up?

Now that I have a capable rig able to load fast, run fast and display fast, I want to start spiffing up the visuals a bit. I'm not at all familiar with what's out there vis-a-vis "eye candy", so I thought I'd see what you all think about that.

I'm mostly looking at three areas at the moment: crew uniforms, environment, and sub skins.

At the moment my enabled mod list is the following (in case you know of conflicts between your recommendation(s) and these:

GWX 3 Wilhemshafen,St Naz,Schluese and xtra ships V5
