Quoting Matt D.
10 would be ten times the speed of sound, not light. Modern technology hasn't advanced that far yet. As for the Makuta, fantastic work! First off, he's bigger than Leviathan by about an inch and he's got a good story behind him! My one complaint is that there's a little too much evidence of Takanuva still in the moc. I'd suggest using more black in the piece to make the color scheme match up better. Also add more to the torso. Right now you've got a good idea, but now is also the time to look at every angle and see how you can improve on it.
I would add more black but all that is left is to take apart the Jetrax and the Rockoh.
