For your inspection...

Hope this blur is better to suit your needs. 
If so, then I'll creat the others.
Also, I'll save the new ones as a .png file
Very nice blur, you applied even less blur than i did. But, that's fine because it looks better than mine now.

Anyway, the blur softens up the background just slightly so it's easier to look at. It also makes it look more like a background with some thought put into it, instead of obviously a region of a screenshot with some text on it.
Running a comparison just above this text of the background slightly blurred by you with blowfishes unblurred background. Yours more looks like the candidate for being the first picture you'll see when loading the mod in the launcher.
You should do what you did earlier and do all those examples with the different fonts with what you did with the background.
