Not a fan of that download host, but I finally got the file.
Not bad for a start. I would suggest getting rid of the "letterbox" black bars top and bottom. You can either crop the final product so that it doesn't show, or change the "lock aspect ratio" property on the footage you took from FRAPs when you edit it.
Although, I can't recall if you want to lock the ratio or unlock it... one or the other, whatever your editing software is doing, toggle it to the other. That should get rid of the bars.
