Maybe that's supposed to resemble a giant crayon? If so, I'd shoot from a lower angle so the top touched the sky, make the sky blue and desaturate everything else. Background has some odd texture to it that looks too much like PP effects for my taste.
i don't see the connection to crayons or colored pencils. Even if it is done using these mediums it would be good to have a colored pencil there to show this.
I am dying to know the background and details for this one. Looks like an oil painting. Foreground with the texture of water and rocks is making me much happier than the greys and blacks in the background.
There is outside the box and then there is outside the box. This is the later. Unfortunately, it fails to have a solid creative impact if only because the effect is way too subtle. However, as a unique entry, it more than meets the criteria in this reviewer's opinion.
