[tutorial] Still Having Trouble

I redid Unflux’s tutorial again and followed every step carefully. I finished my logo and it did seem to be some what better than before. But i did encounter a problem which may lead to the correct result. In the tutorial, Unflux said you had to duplicate the logo layer by Ctrl+Alt+Up arrow. I did that but it only seem to refresh the logo image (is it suppose to create more layers in the layer window?). So what i did was manually duplicate the layer by selecting duplicate and pressing enter 10 times. This maybe the problem since the logo didnt seem to take on the 3d perspective.

If it wouldnt be too much time, please take a look at my psd file and tell me how it can be fixed in the context of 3d and making the edges smooth. Thanks.
