Here's my suggestions to make it look less like a gunship, and more like an FS1 corvette.
1, detatch both wing and engine nacelle sections from the main body.
2, detatch the wing extentions outboard of each engine nacelle, from the engine nacelle
3, reattatch the engine nacelles side by side and at their same distance back on the ship, but slung underneath, possibly adjusting the front end of each nacelle so they contine to slope upwards towards the main ship body.
4, reattatch one of the outboard wing segments, underneath the engine nacelles, aiming downlards like a fin
5, extend the main engine block (the widest area of the main body) back by about 50%, possibly adding a slight indentation where it ends right now.
6, turn the raised dorsal section (currently sitting on top of the main engine block, and which appears to have 3 small engines on the back) into a superstructure, possibly topped by a radar dish (a la Fenris) and have a few single-part anti-fighter turrets mounted on the sides of the superstructure. The 3 mini-engines currently on the back of this section would likely be deleted.
7, add additional details to the currently-flat pannel sections, drawing insporiration from the Fenris and Orion designs. Be sure to add some flank single-part turrets and missile batteries.
