Looks awesome, though it looks a little too close to the Imperial Aquila from Warhammer 40k. Unless that's what you were going for. In which case, good job.
Well, the imperial aquila is yet another thing GW "stole". The two headed eagle has been the sign of the orthodox christian church and as an extent, the Byzantium. This soccer club originates from Constantinople, now renamed to Istanbul, which used to be greek and the center of the Byzantium.
