Your composition lacks visual hierarchy. Everything has equal detail and value distribution. You need to pick your focal points of the subject and push their priority way up while surpressing everything else. Quickie:

Note the positioning of the character, sky line, road and rocks. The character is at vertical and horizonal 1/3rd lines in the composition, the rocks sit primarily around midpoints in the image, deprioritising them a little, sky sits in the top 1/3rd of the image, road comes from the bottom of the piece and follows the direction of the rocks and character, then turns back into the picture to lead the eye up to the sky.
You seem to have chosen a very tricky lighting environment. Green hills in a red ambient light should actually end up very dark and desaturated (I think...?). I pushed the green a little more towards red and grey in some places, but now that I look at it, it should probably be taken a lot further towards a dark, warm kind of olive, yellow and/or grey. The green is really popping out the most at the moment since it complements the vivid reds.
I added the rocks as a kind of suggestion. They share the relatively cool greys and fleshy highlights that the character has, which to me creates a conceptual relation between them. Both are harsh and unyielding, both are directed forwards to the bloody sky. Whatever you choose, though, you should make sure theres enough visual interest in the piece to break any repetition. Otherwise the eye is just going to skim it.
The lighting in mine is kind of messed up. There's 2 basic sources, the red horizon and something off top left. I kind of like the strangeness of that, it feels alien, but really it'd no doubt be stronger if you just went with one or the other.
Also, why are you posting your WIPs in that giant white frame with half of it empty? Just post the piece itself.
Keep going
