Just a slight update.
I've made the tractor beams that are located on either side of each shuttlebay, and I've redone the ventral saucer phasers to account for line of sight due to the warp engines.
I'm currently trying to think of a design for that part of the ship that runs from the bridge to the impulse engines, although, to be honest, I'm not sure if I should even include that on this model.
Sorry, no renders right now, my mom's on the main computer, and that's where I have all my model files. If I had a place to work with my laptop, I'd be working on the ship right now.
