I loved the game and your part in the Dan Pos video. The 2D sprites nail the perfect balance between visibility to show a point of interest and blending in to still give the player that "aha, I found something hidden" feeling. The camera detection is sometimes a bit buggy, but it's not a huge bummer. I was very pleasantly surprised to see that you can actually view your pictures and they even get saved to your drive. The constant side quests are a nice addition, giving some extra reason to explore the beautiful environment. Overall, the game reminds me a lot of "Alba: A Wildlife Adventure" and "Penko Park" in all the best ways.
If you plan on taking this game a step further, you could add a photo album of some sort and maybe display some real-world facts about the animals and their habitat to add some educational value. As seen by the example of Alba, these kinds of games can even be commercially successful if sold at a reasonable price. One thing you should definitely add regardless is an FOV slider though.
In my opinion, this game has a lot of potential, but regardless of whether you decide to continue, you can be proud of what you created :)
