Detail: Detail? What detail, no offence but this is a terrible spray. It's not trensparent, it's completly over brightened with no attempt to darken it. This is a 2 second job of finding a image off google and uploading it. I would dissaprove for spam but instead I'm going to help you try to improve. I suggest you read, here is the Link *click me*. Have a good read of the rendering section on there and make sure you read the whole tutorial.
Originality: Lot's of pokemon sprays before, so not very original and this is a poor example of one. Try to chose better images if you are going to make more sprays and spend more time on them.
Style: As said above, there is nothing to really rate this on, the only style here is the image, which you didn't make, so I can't rate this section, so I'll leave it at 5 for this.
