Express doubt and persuade

Albert: Hi Arnau, what on earth is that?
Arnau: Oh, I got it this afternoon. What do you think? Do you like it?
Albert: Mmm... Yes but I'm not convinced.
Arnau: Don't you think it's interesting?
Albert: Er, sort of, but I'm not sure about the body of the person.
Arnau: Oh, come on! It isn't that bad. It's really colourful and beautiful. It's good to have a new picture in the house.
Albert: I suppose so.
Arnau: Don't worry, it'll be fine. It'll grow on you.
Albert: Ok. We'll see.
