Ditch the wings - they're too skinny, and I don't know that I'd want only two of them...
instead -
where you now have two large projections, top and bottom, have six such projections, flattening the top of each for eventual turret placement. For the combat role I'm envisioning this ship for when arming it, it'll be more important to have more (smaller) capship turrets than to have a couple large ones - it's not going to be designed with the primary goal being to slug it out with large capships at close range - the most effective anti-capship capabilities will come primarily from the twin dual torp launchers at the front with their deep. As the (venerable) part denotes, it's an older model that's seen a lot of service, and it's a bit on the smallish side for entering into grudge-match battles, but it should still excel at dispelling patrol craft, gunships, corvettes, light shipping, and other such larger craft, clearing the way for its larger siblings to dish out the real punishment. About what one would expect from an old (now designated light) destroyer role - capital escort with some decent, if limited, anti-capital teeth.
Don't worry so much about the other turret locations, I'm imagining I'm going to be moving them around a bit until I'm satisfied with the field of fire and PD coverage. For the forward launchers texuring is all you need, no need to put holes in it
You might want to coordinate your turret generation with PeteyG, he's making some Aera turrets too.
