Make sure you have AA on when you're writing your main text, not on pixel fonts though - You got that right ^_^ Also, try doing more with the BG and not just brush it. Uses filters, C4D, abit of brushing and afew colour balance/gradient map/curves layers. Just leave it without a border, or add a 1PX black or cut bits out of it and make it your own
decent. maybe pick a different size (smaller) or add more effects. blend the render a bit and yeah, turn on anti-aliasing for those fonts. keep working on it, you'll get good in no time
