The "old guy" needs to be identified as the animatronic character that he is ... otherwise your audience will wonder why the focus of your ad is a mean looking old fart. Otherwise, the dust cloud coming off the herd needs to be a little more pronounced, yet merges well with the prairie grass and your main character. The horizon looks especially good (always hard to make a realistic looking horizon at night) ... but your stars need a little work.

Overall ... a very impressive effort http://www.talkgraphics.com/images/smilies/smile.gif
