Obviously it shows that you're trying and making an effort to do something like this and it may not be an easy thing to do as well. One other suggestion is to 'stand up' while doing this, perhaps doing so, the 'flow' of signing will become more graceful. Keep it up and the more you do or practice, you can go only in one direction and that is; improving as you go along. Other than that, have fun doing it.
