Cursive font doesn't do the trick. The graphic is somewhat dull. You might want to slant the phone a little bit and make the earth appear to be moving or something. The "free worldwide text messaging" is good The "Go" word is somehow outplace. Make your title stand out. >> 3 out of 5 Not bad.
Really don't like that font you used for 'Textoozle' couldn't work out what it said at first, otherwise it looks good.
the background is cool, the first effect doesnt look good, and i dont understand what is write there ... TEXT what? and on the circle same effect ... try changing the effects, then post again, showing us your new banner
try to work more on the background. try a gradient and use some vector shape, or some dotted patterns
