Ouch. 7? Is it because you don't recognize the characters or just because it's not well done? lol. You don't have to answer.
OT:
Om Nerabdator - cool pose for the character and the mecha. The stroke for the R and L are way to thick though. Background needs some work since the right side is kinda plain. Adding some cloudswould make it look really good. 8.5/10
