Hate to hear about your lost work. Always sucks when that happens.

Maybe a grille design along the lines I crudely illustrated would work for the collectors, with a glow of some kind in the recesses.
I would have to agree with WileyCoyote on the windows, even on a Nova Class comparison those would be a bit big, about half that would look right. Also the bridge and engines look too small in size comparison to the rest of the design, would enlarge those about 25%, once again keeping the Nova Class in mind.
Don't mean to critique too harshly, Just my honest opinion the way I see it, just suggestions.
I really love the basic design and would like it to see it's full potential. Can see a great inprovement in skills since your last work so far.
Good Job.
