A text description of your upcoming creation is generally useless, unless it is REALLY well described or supported by screenshots. If you don't want to give away too many details of your creation before release, take a screenshot from an interesting angle, or edit your screenshot to hide some detail. If you don't know how to take or upload screenshots, there's countless tutorials on that already.
