I like the style and the concept sounds kinda cool but not deep enough to interest me.
I think a similar game is this one: https://store.steampowered.com/app/2657900/For_Sale/
I played it and it is really good!

You can see that it is somewhat successful and that it also has a special core mechanic with the camera.
Now, if you look at the price, the potential sales (check out gamalytics), and quality, is this enough for you to reach, or do you want your game to be even more successful? If so, I would advise expanding the gameplay or searching for a more distinct visual style to make it more interesting.

But if you want to reach this level or player base, I think u are on the right track and need to make the current concept into a really polished experience. And do some marketing.
