I definitely think elegance and 'sweeping' should be how someone should describe the Elven ships. As long as the main hull integrates with the very attractive, swooping prowheads and towers you'd be on to a winner. Definitely keep those aspects! Maybe both fore and aft being tiered or swept will look better, the more I look at it the less I'm convinced one end or the other should be lowered or flattened. Perhaps a slightly more shallow curve but still tiered?
I REALLY like the look of the Dark Alliance galley there. The proportions are great as-is, but I don't think a little beefing of the yard (that bit on top of the sail that it hangs from) would be bad at all, especially if it helps secure everything. On oars - they seem rather thin. I expected those pieces to be more of a wedge, angled downward from the hull, making a larger area to attach to the hull. Will there be space beneath them once they're attached then?
Dwarfs? Well I might not need any myself, but I almost wish I was collecting a fleet all over again - those are crackin'. I might be tempted to make the upper superstructure a little more angular around the top; rounded when viewed from above but flat-topped so angular from the side, as if the tiers are all traversible decks, but that's taking nothing away from how good they look now.
Thumbs up so far! Now, how are those Orcs doing?
