OK, here are a couple of areas:
In your own description, you said you knew it was sloppy. It may seem obvious, but I would recommend practicing until it's not sloppy. If you know your own shortcomings, then you aren't likely to get any useful help from anyone else, as they will probably just point out things that you know already. However, if you practice until it seems perfect to you, and then ask for help, then the criticism you recieve will inevitably be useful to you, as it will illuminate areas that you weren't aware of yourself.
You haven't got any patter. To my mind, the ambitious card doesn't work very well as a silent routine, as there is no drama and no tension. It's just a card moving from one place to another over and over again with no meaning behind it, and that quickly becomes boring. The one exception to this would be if you were performing a highly difficult and technical routine aimed at magicians, in which case silence might work so they can marvel at your move mastery without misdirection.
I don't think it's worthwhile criticising your moves, as you said that you knew it was sloppy, so you probably know they weren't brilliant anyway, but hopefully the two points I've made will help.
