Nice neon effect mac but it might be easier to see what you have done if we could see the original image.
Also, the hand image with the ball and the straw or whatever it is, is great but the light rendering isn't as good as it could be. The ball is reflecting the hand at the same angel as the camera sees it and with no orbital reflection warping (if you understand what I'm trying to say). You should try fliping the reflection vertically and then using the "liquify" filter to add the warped reflection that the ball would produce. Other than that it look great.
