Good Start,
May I suggest:-
The sword should widen slightly as it gets down to the tang (the bit inside the handle)- the principle use of this type of sword was rather like a long chopper.
Later medieval swords such as the rapier or epee had devices designed to trap and snap your opponents blade, so your guard is accurate- but would have faced the other way for practical fighting, and would only be of use against thin blades. The pomel on a sword helps to counterbalance the weight of the blade, so was often a large heavy lump of metal. Often the grip was made of thin leather wound spiraly round a wooden grip or of fine silver wire which gave better grip when wet and sticky- uch.
