I Imagined this design as I went from drawing the head down like I do with most of my robot drawings. I think I'll call it the Hell Razor. The head has outward pointing horns and is armed to the teeth. I also tried to make it look like it was boosting along the ground like the mechs in the game Armored Core 4. As for the flamethrower, it's either being fired for intimidation or it's passing under some flying target.
