Logical or not it's a beautiful or ship. It's the most beautiful ship on any Stargate show, clearly from a different culture than the folks who built Atlantis. Just like cars built in the 40s are very different from cars built in the 90s. I wouldnt say "odd looking" I would call her exotic.
My favorite feature is the observation deck. So many ships in these shows are clearly only made for war but Destiny actually has a place where people stand and marvel at what's out there. Earth ships from SG are very clunky and ugly. Gua'uld ships were pretty and "odd looking" from a hollywood space ship perspective.
