Hmm...the picture of Goku needs work...the edges look very chipped and rough, and throws off the whole pace of the banner...I'm not quite sure what the "shadowy outlines" at the ends are supposed to accomplish, but they don't do anything but hurt the pic in general. As for the choice of colours, I'm not really a fan of that tint of red...it looks tacky more than anything...although I DO like the 'inner' text colour...
Good effort, though..Keep practising!
