It's been a while since I've been on the forums, and even longer since I've practiced pixels.
I'm making a knife icon for a video game. Here was my first attempt.

Then I tried to eliminate the black border in order to get more realism in the look.
Added a bit of shading and AA ? I'm not sure if I did the anti-aliasing correctly, though.

I would like some help on how to make the knife look more real and
professional? for lack of a better word.
Thanks

**EDIT** by the way, what happened to the forum? It looks generic..
