It's looking nice. It seems, however, that you're getting semi-correct anatomy on the people, yet the faces are anime and lack expression. I'd suggest adding more realistic facial expressions and convey what they are feeling through their emotion. They're going through a desert at night, being chased by a monster. Make them scared, worried, etc.
Also, is the hill going straight down? Because the footsteps flow straight down, whereas in the desert there would be bumps and clumps of dirt in different places, making it not a smooth walkway.
I love the monster's design! Good luck, Moz.
