Ah, the age old classic of the "Where's Waldo" picture book. Testing your artistic skills by blending in a figure to historical paintings.
Unfortunately, I quickly lost my patience with it and randomclicked the whole thing until I was simply no longer interested. The problem is that there's no sense of difficulty progression. You're already playing as hard as you can.
The hint system did its job. Unfortunately, it doesn't actually help me maintain interest, since the next task is simply to "Find the next thing".
I can tell that you're an artist trying to solodev a game. You will benefit greatly if you can find a team to put your artistic skills to work. Come back and try again in January!
