i like tthe 1st and 2nd, the third i dont like it cause of the drops u placed ,thou it is a nice idea)
Now in 1st why u dont try to make the text more clear...
in 2nd i like the colours better becuase the image combines better with the samurai...thats my opinion...
Also something that ive noticed on 3 of them is the small spot that u have in right bottom corner, its a bit annoying...xD
