What kind of effect is it?
and how long have you been doing it?
have you performed it live many times?
Make sure you know the ups and downs advantages disadvantages of the trick.
i made an effect i did what Wayne said you should tape yourself near the beggining and a year later tape yourself doin that trick their will be many improvements and changes.
im just getting ready now to submit an effect or so.
but its great to be confident.
sorry if i made you less confident.
