I think the big ornament at the bottom is excessive. Unless it has a name or something (you know how those RPGs are) that gives it a need to be like that, I say go with something lighter, smaller, less distracting, and more practical.
The sword could use more interesting and convincing colors. I'm not sure what type of material you were going for with the brown, but if it was wood, stop there and change it. I'd feel a lot safer having a metal handle and handguard than a wooden one, and the color you look like you'd be using for it isn't very natural. Try decreasing the saturation and looking at the material you decide on in real life. The metal bit could have been at least rudimentarily shaded with flat blocks of color to indicate tilt and some high contrast for a metallic look. Also, in general using pure grey is a bad idea. Give it some tint to contribute to interest and mood in the piece.
While you're working on a sword, look for references for different types of sword. These will help you out a lot with your linework and form and should give you some ideas for details and shading as well.
