I can not complete the bonus game

Hello dear fishies, I am at the end of the bonus game. He says to find this woman. But when he drank the ampulle and said this to me the final credits appears and I can do nothing more.
In the SG I see the solution with a large pictur and another minigame in a shelf(?)

Am I the only one with this problem?
Please help me if possible.

Happy gaming

The only thing I can think of is if you go into the collectibles section you may find what you are looking for.
I lost all of my progress at the very end of the bonus game and nothing that I had collected or had done saved. It seems to me as though the collections section has a few more mystery items for you to decode.
Hope this helps some.

Thank you Poof11, I found it. The portrait puzzle is in the Collectibles under the red curtain with "46". The second puzzle is in the left door looking like a safe. Not I try to solve it. Wish me good luck. Hihi.
