That MOC looks awesome, I like the massive, bulky feeling to it. My only suggestion would be to give him red and not silver eyes, since they would create a contrast to all the silver and gunmetal on his upper body and would help to define his head, but that's only a minor detail. And congrats on MOTD, you deserved it.
Impressive Bio build, nice to see something other than a self moc or a toa, or even a makuta. Not that those aren't cool, of course...But anyway, It looks very imposing, and the huge shoulder pad things look really good on it. It looks very technical. I wonder if a minifig would fit into it, it would make a good mech. Congrats on MOTD!
i think this is pretty cool. i used to make things out of bionicles but most of my good peices are put into a Halo Elite(credit to the guy who made the Spec. Ops. Elite here on MOCPages with instructions(i havent posted mine yet)). but with the only Borahk that i got, i turned the teeth around and you could rip peices off of the other bionicle you were "fighting" lol. you should do that with this, it would make it look even nastier then it does.
