It's cool to see your motivation., keep on!
What render mode do you use, because it might be the lighting, but your textures look a bit to overrealistic to be in the game imo (this might sound weird). You should try out some sculpting programs, to get the depth on your item textures, cuz right now I see a diffuse texture, but no ambient occlusion or normal map. Maybe you've added them, but by using photoshop tools to build up a normal map from a texture, or d'you tweaked the contrast to get the AO and that doesn't really works. Well it works, but that's what they used on the building textures for warband and as -I hope- you can agree, that looks a bit shitty.
I'd say, try to avoid hard edges, that can be solved by -like I said- sculpting your normal maps.
Also, try to look at the goodlooking armours and weapons in warband, and explore their textures in OpenBrf to see how they are made.
Still, great job, I would never have the patience to do all of those assests, gratz man!
