some real cheap and basic video work here would go a long way.
get a surface to use, idealy not a bright color, not a dark color, something more neutral, wood grain works. a cheap table or even just a bored to place down would be perfect, you want it to not be shiny, shiny is bad for cameras.
then you need to get a couple lights, depending on the scale you may only need one light, you want it to be bright and soft, you can make your own soft light using a normal lamp and some paper, how to's all over the web for that, get that going for a consistent light, that doesn't wash out any color or cause glare.
those two things alone would make the framework of the shots look much much better, chances are you can do this all for free with stuff around the house, if not 10 bucks could get you all you need. after that like the above posters said, work on your presentation, don't just perform a trick, put on a show, make us feel the magic. let the trick unfold, build some suspense, and guide us into your rabbit hole, don't just kick us down it.
