This is amazing!! I love the concept and your illustration techniques are just awesome!
I will say that the tone comes off as more creepy than humorous, like the kid is about to feel some serious trauma. I actually think it might be the mounted rabbit head... I'm not sure people would mount something like that, so that makes it seem like it's specifically Bambi and Thumper, not just any deer and rabbit. Or like... who is so proud of killing a rabbit that they mount it on a wall?
I think the connection between mounted animal and the characters on the screen will still work without being a direct parallel of both characters.
So I might describe this as over-the-top creepy, but I actually think that's pretty awesome! The two animal shadows on the wall are fantastic, and I'm loving the feeling of "about to realize"! But if you want to take it down a notch, I would suggest removing the mounted rabbit (maybe include a stuffed rabbit on the couch?)
