I'll be making a tutorial about clipping masks using photoshop, so it may be a while. :x I'll try to get it done either today or tomorrow, just depends on if my computer wants to die. D;
And that is nice I must say, the text kind of ruins it though, it's a bit big I think. Also, try working with good quality renders, since the render you've use is a big speckly, but it still looks good though.
