poor execution. i think when you go for something like this, you gotta really go for it, and make it 100% convincing. (ie: not use the pixelate filter in photoshop for the old-timey 8 bit graphic look).
well, it seems as though this is part of a series. so, i'd imagine it's more a poster for the series (featuring the sonics) as opposed to a poster for the sonics.
