Try to improve up on your camera angles. Zoom in a bit more and more your camera around, don't just keep it still but turn it around a bit.
Don't use Movie Maker. There are a bunch of free trials for all good programs out there, I'd recommend installing one and trying a quick project inside of the time limit you have.
Another downside is you cant have multiple soundeffects in a single video, you'd have to reimport an already-rendered video. Very tedious. Videos need sound, so yeah. Ditch movie maker asap.
