jx is totally right. Have you not seen the 234986239 cake shows on tv nowadays. There's so many different things you can use to make a cake look however you want. Marzipan (though not the tastiest of ingrediants), model chocolate and fondant to name a few.
The wedding cake is, as JX said, a reflection of the couple and the theme of the wedding, whatever it may be. I think this is a beautiful cake and was well made. I'm guessing the brown is supposed to look like wood grain (based off an episode of Cake Boss i watched yesterday when they made a roulette table). This cake looks awesome and I'd eat it.
