I agree with Vlad, your subjective impression is not sufficient to be able to provide an answer whether you will pass or not. Candidates sometimes think they did badly, overweighting some mistakes and pass. And sometimes think they did great and don’t pass, since they have not noticed some mistakes.
An interviewer may ask “Anything else” when they want you to derive additional creative points for a question. This usually happens when you are not particularly structured, or at least you have not presented all the macro areas the interviewer expected.
Hope this helps,
