My logic on the crude look: The Orsimer are known for being, basically, a corrupted race of elves from when their god ancestor was eaten and corrupted into the "Daedric Prince" Malacath we know of today (Daedric Prince here is in quotations because he isn't, as I understand it, regarded as a prince by the other princes, but whatever.) Their god was corrupted, and so to were they. It makes sense that also their works would be likewise corrupted, made harsh looking. They don't care for looking good. They care for strength, and toughness. Therefore, physical appearance is low priority, if not outright ignored, where crafting weapons is concerned. That being said, I see a mild resemblance in their armor style to that of the Samurai of early japan. Leastways, it seems slightly Japanese to me. The weapons, not so much. The edge of their sword looks like it's already been hacking at some heavily armored trolls before being put in the shop. I'm not expecting good looking weapons from them, but I can see what you mean by practical. The armor is good, the weapons need work.
