Project GHOST: Detective Peter Roberts (callouts and initial sketches) concept art

Warning: The following project contains paranormal elements, gore and dark, mature/sensitive themes.
The art is part of a personal passion project for a potential horror game that I also submitted as part of my final year 3 university project. The narrative centres around hardboiled 45 year old Detective Peter Roberts, who explores a now abandoned high school in the forest of an old historical town called Rivenbrook twenty years after 1998 (the setting is inspired by Norwich in a fictional England). Peter tries to uncover what truly happened to Flynn Reed, a 17 year old student who was found dead by hanging two weeks into the search that dark winter, which Peter had taken part in when in the police force himself. The case was ruled as a suicide, but was in fact a homicide, much to Peter’s disbelief. What were they hiding from him?
I will update, shift around and separate out character art, environment art, etc. as the project goes on.
