You know, I've read enough Minecraft FF that starts with the player suddenly waking up on the Overworld to make any that starts the story with that scene bore me down. Try starting before the warp or after the warp, giving the player some sort of background. I can't really imagine how your character look like without any hint of appearance existing on your first chapter, and that hampers my ability to choreograph the story in my imagination, which is bad.
I don't really know whether this is constructive or not, but I'd appreciate your work more if you can avoid cliches that many uses so that your story is a fresh surprise for the world to read. Fresh ideas are nutrition for our mind.
