lol uh... try using it with a different render, that's the point ^_^
Not bad result though.
I just wanted to try the tut out and i had the same render =p i will try it will another render to see how well it comes out. Now ive tried it i can look for a render that will go well with it. Because judgeing by the tut you will want a render with nice bright colours which goes well with each other. So now ive done it if i come across such a render ill try it out =p.
In the mean time heres what it looked like with the clipping mask.
