Oh and quick tip and heads up.
If your new to making models for SH3/4/5, dont rely on the assigned smoothing groups in your modler, where you want 'clean edges' in your geometry its best to break the verts or edges at the seams (e.g detach the faces to element in 3ds max)
AFAIK by default Sh3 and 4 smoothes over eveything blissfully ignoring obj smoothing information.
(at least this seems to be the case with Dats - im not sure about Gr2 in Sh5), so breaking the verts is the only way to control smoothing angles.
If you dont do it this way, even the most beautifully crafted model (such as your vosper) will yeild some ugly anomalies once in game.
In your last render. check the darkened area at the front of your Vospers Port torpedo tube - that is what I mean.
But superb work, unit models up to this sort of standard are gold dust...
