You might want to show it either without textures or with textures that have been more then slapped on here, because that slap on is really distorting the view of the actual model.
EDIT: Wow, if that is what the actual textures look like that means the developers did some very clever texturing to the vanilla models.
Also, might I give you a bit of advise on what I think I see there, two rules for Rheinland ships.
1. Rheinland ships are covered head to toe in green armour, that means no "exposed" components.
2. Rheinland ships use no colours other then varying shades of green.
For a ship of its' size, I'd say your model is lacking in detail very much. It it were scaled down it would be okay for a mid-sized freighter. On larger ships your textures and components should be smaller, which creates the illusion of the ship being bigger without having to compare it with anything. If you didn't have a comparison model, I'd say the ship was roughly half the size of a Humpback.
