Not to be a party pooper but the most common English terms would be two handed sword, longsword or greatsword. Broadsword is generally used to refer to basket hilted one handed swords to keep them apart from the rapier spardoon or smallsword and not the cross hilted one handed so-called arming sword.
Claidheamh mor means big sword in Scottish gealic, shortend to claymore, if referring to a two handed sword they generally have a v-shaped crossguard It can also mean a Scottish one handed basket hilt sword.
Espadon or montante in Spanish
Spadone or spada longa in Italian
Langes schwert, Zweihänder, Bidenhänder or Schlachtswert in German depending a bit on the size of the sword.
French I think it is called “sword of war”… but in French of course, though don’t quote me on that.
Sorry about that I just want to educate the world a bit
As to the design I think it is pretty great, though I would personally have put parrying hooks above the ricasso just to make it feel safer to halfsword, mainly because it has a quite short blade. And the render is really, really pretty as always
