Well first of all i would say that remove the text from the tag. Its not at all helping the tag. Now comes the tag. Yeah they need some tweeks to make it more good. First of all i will say about the color. Tag color atm seems to washout .Add more vibrance to them. To improve it i would suggest you to add one more color to the tag. Detail in the tag is also somewhat low. You can add star stocks at color dodge to get some nice small dots or add some space stocks to screen or lighten. To fill up the left side add some splatter brushes and clip mask them. Here i have a tutorial for you which will help you out.
