even if you can't draw new maps, making patchworks can be done by evryone, so what's the problem?
find a map -fs2 or internet- you can use to make the borders and maybe some lines to make a grid, open paintbrush, photoshop or whatever and do it. The point is how you imagine it, and then invent a way to do it.
Windows can easily be placed on the nose and the rear angle, just modify your texture (again, a patchwork will work fine if you can't draw by yourself) and if you have problems with uvmapping use Lithunwrap
and with monothone I just mean that it simply is a very basic texture just repeated to cover oll the polys, some texture variations, mech elements, other stuff, will improove a lot the whole thing
