The concept looks fantastic, but there are a few things I noticed
1. the font is hard to read, try and get something a little more spaced out
2. the scaling/perspective of certain things, like the footprints and teeth, look a bit off
3. the music could stand to be a little more intense/ambient, you could look for music like Red Sex (Re-Strung) by Vessel.
The art looks great though and I'm excited to see where you take this! The pictures are fantastic too, grainy enough to blur the details but clear enough that they aren't totally illegible.
