Yeh I would turn the bump down a tad, it probably looks washed because the ground texture gives off a similar colour to the sky?? like the leaves are very similar shade....I agree with Gen, the angle is a bit off. How big is it going to be mate? something else in there for scale would be good too, like rusty coin or box of matches etc
