If you're going to want to use this on a Graal server, I suggest you blowing it up and reconstructing it a bit bigger.
Proportions on Graal are all wacky. Your sword is going have to be much bigger if you want to get any detail out of it.
I suggest keeping sprites handy on your scratch board (aka, where you're doing your random pixeling) so that you can drag your item to the character for reference.
Edit: Try to take the criticism people are giving you (no matter how harsh) and recycle it into improving your work. They're the ones who would be subjected to your graphics on a server, so you'd be wise to work in their favor. Take what they're saying, and fix it up!
