A few refinements? As in what exactly? I guess u are asking for creative critizism. If that's the case read on, if not skip to the next post.
Warps are too big for the aft hull. The same can be said of the saucer. The Warps being 90`canted, dont like it much, although it may work... Gut feeling tho.
Overall, yes, go for it. It'd be a welcomed design (different enough) and I'd download it with a few refinements.
Besides, most of your ships are top notch anyway. I'd d/l it regardless.
