Make the solo a lot more interesting (musically) and take out the double bass sound during the section @ 1:09 and I'd say it's a pretty good little track. The evil laugh was an awesome touch.
Fun fact: The evil laugh is actually from one of my friend's videos. I got permission to use it (he put the video on Creative Commons on Youtube, so anyone can use it really) and so I used it to fill up what would have been complete silence. Here's the video.
