This will be in order of the things that I clicked in my video
1. At the start, "Ahhhhhhh!!! Where am I?"
2. The first picture,"A painting that shows several people in a living room", "They appear to be waiting for something" might sound better
3. The third picture, "He seems to be an important person", there is nothing wrong here but I feel that you can make it sound better int he perspective of the main character "This man seems to be an important member of the mansion, I wonder who he is..."
4. The fourth painting, "The painting shows a few members of a royal family"
5. The rotten food, "Whats that awful smell?", "Ahhh!!!! It's a plate of rotten food!!! I wonder how long has it been here...."
6. The key, "They seem to be parts of a key....", "Maybe the key is what I need to open the doors..."
I feel that maybe the using of Ahhhhhh is actually not very appropriately, maybe you can see how subtitles of Resident Evil games are like when the main character approaches something with shock or in care. I will be looking forward to the game if you ever plan to make it :).
