21 second dark forest Warm-Up

Done as part of a practice session with poses of 21 seconds in length. My current goal is: Make my one-point perspectives more faster and good-er. Hi everyone, I'm Polyvios Animations, and this is my latest warm-up sketch. That's a forest. I'm really trying to tell a story with this one drawing as shown. The story about this forest that it's really cool-colored and darker and gloomy in atmosphere and tone. So what do you all think???
