Need to go bigger with the type(all the way across and nice bold type like this, don't make it too short tho), clocks will be fine as type should be the focus so make it bigger so it fits across the whole sticker.
I'd also do type in white (or really really light grey) so it stands out more as that's the point in the stickers, advertising.
Remove the grey stripe above the clocks and move the Retards Club down closer to clocks and bigger too so that goes most of the way across. I'd straighten that slightly (not too much) too, so it flows with the clocks.
