That is a big ass rock. However, I'm not sure what the point of interest really is. I mean...of course its the rock, but the rock is the same color throughout the image making it somewhat monotone in nature. I feel that the rock might have been a good subject for a wider angle shot showing more of the scenery around you. 5/10. I will say I really like some of your other shots on your flickr.
