My OC Gero's Sword: Hikari

So I decided to purchase a sword line art to do a reference picture of my OC Gero's weapon. I wanted the colors to match almost like a thunderstorm since Gero has the ability to control lightning and any electric based attacks. The silver and black are the clouds, and the gold represents the lightning. 

I tried drawing lightning coming from the tip of the sword, but it did not look presentable so I went along without it. 

The line art of the sword was done by: If any of you have not watched him, you should. He makes really great weapon designs and needs more recognition. Thank you again for the sword, really do appreciate it ^-^
