An unwelcome encounter in the dark.
I love the impact of this piece. I feel like a deer in the headlights, staring at this figure emerging from the darkness. Your composition is very powerful and effective. The high values in the face surrounded by the red jacket keep the viewers' attention fixed on the main subject. The way you have targeted the face by morphing the shirt pattern into concentric rings really helps to lock the viewers into the gaze.
Of course, on the off chance that we can break the stare, we are witness to the bloody knife and the surrounding murk of the forest. I enjoy the fact that, although his shirt so clearly stands out from the rest of the surroundings, you have suggested how at home and deadly this man is in his element. His arm and legs melt into the background, and we know that if he had really wanted to remain hidden, we would have never seen him until it was too late. The glowing eyes and faces in the trees enhance the sinister mood of the piece.
The texture of the support and roughness of the pastel and paint strokes suit the theme of the backwoods excellently.
I only have two suggestions: Firstly, adding some lighter highlights to the foreground branches might have allowed them to stand out better and guide the viewer's eye into the painting. I doubt whether doing so would have detracted much attention from your main subject as the composition is already so strong. And secondly, you might have introduced more rough texture into the piece by using "sgraffito" or scratch-back in the oil pastel parts.

It was a pleasure to view and critique your work, and I look forward to seeing more from you!
