What I think the problem is here is that you are not using any bright or dark colors only midtoneish colors. You don't nessesarily need to go all the way white or all the way black, but a wider range would be nice I believe.
I also think that since this piece looks pretty linear in terms of light and color it has no place to rest your eye, no "focal point" as some would put it which makes it less interesting in general.
I really enjoy this drawing tho, the anatomy looks ok enough and the forest looks like it has some depth to it which I like very much.
