you should have some one you can practice the trick so you could tell him the method every time you think of sdomething or add something to it they might go oh ididnt see you do that or wow i didnt see that sleight and so on.
It's great that you added to the discussion, but can you PLEASE add some puncuation and check you spelling and grammar, so your post is actually readable!? Geez...'mini magician' actually makes sense as a username.

Anyway, most people have already said what I would say about the creation of a trick.
One of the best ways to judge a trick was suggested by Wayne Houchin. Film yourself doing the trick as the 1st version, the raw trick you created. Then after some time, like a year or so, re-film the same trick- same angles, light, etc. Then, compare the two tricks. See how much it has changed, and wheter the change has been worthwhile or not.
Usually, you'll see drastic changes that make the trick much simpler, more effective, etc. Then, you're probably ready to showcase your effect to the world!
