Sorry, but this might be a bit off-topic

I worked on a video explaining the basic idea behind WLM found 
here:http://www.youtube.com/watch?v=jDiu4-xdLKE using a 3D character and 
some slide presentation for use in my country.

Anyone to help make the video very nice and better-looking? My laptop 
really struggled several days to get that short 3d video rendered. Its 
got no voice-over yet. Any help?

Any ideas, comments to make that video nicer?

I'm from Ghana and we plan using it to introduce briefly what WLM is.

Sorry for the 'off-topicness'
