Kestrel CTE-20000 Light Bomber

[Durandal]

As a fellow SU user I can say that this model looks like it may have a few internal faces. The thing which I'm assuming is a torp tube below the cockpit just looks outright odd and needs to be redone.

The ship itself is a bit uninspired and looks like a blockier, sharper version of the Roc or Eagle. You could try smoothing the fuselage a bit using the arc tool.

My advice to you is honestly to do away with this design, and make something new entirely. It can be a bomber, a fighter, or a whatever, but go with something that's more original and brings something fresh to the game, as the CTE line is already covered nicely.
