Good start. You get right into the meat of it. As another creator who enjoys some good old horror in the story, I applaud how you set the scene and constructed the panels leading deeper into the mine.
A critique is the pacing of the reveal. Your build to the monster/badger was well done but for pacing and tension building, the reveal could have waited a beat longer. Episode 1 would have ended on a fantastically suspenseful note if it ended with the panel of the 'scree' sound effect and the bloody cavern.
A sense of dread was sacrificed to have the monster shown at the end of the page rather than a reveal in the next episode.
It's okay to give a bit more breathing room in the pacing, particularly as you do a good job of getting the audience to hold their breath. Let them hold it a little longer, you have all the right setup for it.
