focal needs alot of work man, at this point the focal is your text (wich needs work too). Also i think you blended you render way too much wich makes it hard too see. Colors are very monotone too. Just keep tryin'!
I would have used complementy colors to on the Samurai...many people like a common hue/tint in their sigs but yours takes it to the extreme... too much blending..I like the metalic looking thing in the middle...GJ though!! Props..
