Impressive
This has to be inspired by Amnesia.
I really like it. I'm not a huge fan of this kind of pixel art, feel it looks like low-quality line art.
But that shouldn't affect my score.I really like the facial expression of the guy hiding. Apart from maybe his legs/butt he looks very well, anatomically speaking. The lighting is good and you've done well when shading it. I really like how you put the monster in front of a lightsource, makes him look even worse.
