I agree with the previous comments about wanting more foreground visible. Only thing I'd add is abouthow to achieve that - rather than tilting the camera down, I think it would be better to have shot with the camera close to the ground, for that 'eye-drawing' perspective. I susect that would have provided more foreground and brought the people into the image more, while preserving (or even enhancing) the drama of the overhanging tree limbs.
