How to repair scratches on buffet.?

I have an artisan-made wood buffet. I don't know exactly what is the kind of wood but I know the buffet is polished. Sadly, I hit 2 places with my elbow. Here are some images : http://img690.imageshack.us/img690/1507/phototx.jpg

As I know it's a minor problem and I don't want to pay for a completely new one, what can I do to repair the scratches?

Your help is welcome

Thanks!

u sure the sandpaper will fix these kind of scratches?
