I'm not an expert and obviously i don't know what your direct aim was for the pic but i think:
Lack of colours in both pics (Which i personally don't like because i'm a colour junkie) however it gives a bit of a dark and gloomy effect which i would guess you are looking for.
I would suggest maybe you look at approaching the forest which different angles and heights, forests are great for that.
Great potential for high contrast B&W, or bluetone possibly with burning around edges etc
All in all i like! Please critique my pan picture in return!
