Very nice tutorial, it's sort of like a neon reflecting text. Very cool. Thank you for the tutorial.
On Step 4 instead of having to click on each letter, what I did was click on the duplicated layer with the magic wand tool, then go to Edit > Invert Selection. It will then select the text.
On Step 5 instead of having to fill each letter in one by one, I went to Flood Mode beside Tolerance and selected Global, this will fill the text with the color of your choice (keep in mind that you have to have the Wand Tool selected in order to change it to global.)
