The problem i see in you sword is that the handle texture is surely a really nice job , well , the mesh looks also very good , it doesn t seems to have tons of polys and still looks very nice.
But if you plane to use it ingame , i dont think than anyone will see it once it will be in their hand , also the the texture seems too good to be a 256x256 one. Exept this , for being used not for realtime/ingame purpose , it looks very nice , but if it s the case , you might want to add even more polys.
