There are some great textures in this piece and I love the different brush strokes that you've used. I agree about more contrasting colours needed just to pique it that little bit more. Love the fact that the houses are in the trees, health and safety first
very nice work.
The composition is very good and the scene is interesting but it lacks contrast and strong focus. Your big tree should be the focus but it doesn't stand out since it's colored with the same values as the rest of the scene. For now, the mushrooms are the focus point since the red stands out in the scene and I don't think it's the goal. Just getting some warm brown in your tree and having houses that stands out more would make your scene much better!
very nicely done
