Yeah, I'd have designed her with a primary NX-Class type nose-tip style embedded oval deflector and maybe chosen the following kinds of AWACS pod:
- The Ronin-Class type set of dorsally-mounted phaser canons; or,
- Upgraded Soyuz-Class pods, located both above and below the secondary hull; or,
- Appropriately (somewhat) scaled-down Oberth-Class style extended-range sensor pod docked directly to the ventral side of the primary/secondary hulls (just like the set-up of the three sections of the Prometheus-Class) rather than separate it from the main hulls by any kind of support-arm, with deployable-retractable landing feet/legs.
The two holes in front shouldn't be there. If anything, add the concealed weapons bays like the front triangular spots on the shoulders of the Defiant. I'd pull the nacelle pylons & nacelles themselves far closer to the body of the ship, a-la the "Star Trek: Online" quad-nacelled 'Dakota-Class'.
There's no visible shuttlebays / drop-pod doors for scout vessels for observation missions. Perhaps deploying / recovering sophisticated probes or building & launching their own modern-day subspace amplifiers as they'll be out of reach of their normal "roaming area" of subspace radio for weeks/months.
