By BG I assume you mean the black background?
If yes the background was always black but the blurred area was cut off in the original picture and I made it more rounded to look better.
The font moves closer to the brain ingame which I can edit freely whenever I want, the picture is only here to display the font.
Yes I tried making the blur on the duplicated layer and tried above and under the text, under the text it only makes the "black holes" in the words white not really that nice in my opinion.
I removed the red border around the text but left the inner shadow and drop shadow. (If you remove inner shadow the text completely changes.)
Anyway here's a link of the file, sorry was at work couldn't upload it earlier but here:Link
