Non-PRO Japanese to English Art/Literary Cinema, Film, TV, Drama

Dear ProZ members,

I have a doubt on how to interpret the following sentence. In a cartoon, some students are trying to convince their friend to join them reading stories to children, but he strongly refuses due to a previous experience where he played a princess with awful results.

One of his friends says:
お姫様役のときは個性的でしたが王子様のときは素晴らしかったですわ

I have a translation that says: "Your portrayal of a princess was very unique, but as a prince, you were wonderful!"

However, I feel the meaning could be: "When you played the princess it was personal (as a boy, you didn't feel good portraying a girl and thus it went bad), but when you did the prince you were wonderful!".

What do you think?

Thank you so much!
