Shiny! shiny! shiny!
More shiny!
Unless it's like; a stone sword or something, but I'm guessing it's made of the more traditional steel.
Remember that when shading a steel sword, it is reflecting everything around it, but let's say it's a sunny day,
then the blade would be reflecting mostly sunlight most because it is the brightest source of light.
This is why, when looking at a sword, you don't usually notice all of the other little light particles bouncing off of it;
however, when the sword takes on the shape of a squished diamond of sorts; one side would reflect the sun,
while the opposite side would be reflecting the lesser lights; the sky for example, and since the sky is blue,
you could shade this side of the blade with a blueish tint; which would give it some more character and realism.
To see this for yourself, take a kitchen knife outside and look at how it reflects the light. This could help a lot
when shading any kind of shiny sword. Just remember not to give it too much detail when drawing it, that could
lead to it getting too noisy.
There are many many different situations of course; just use your imagination and some cool looking swords could happen!
Here's an edit to illustrate what I'm saying:
I beefed up the hilt because, like others have mentioned, it was kind of thin.
I also shaded the outlines a little bit to amplify the brightness of the light source.I hope I've helped in some way, have fun pixeling!
