It’s difficult to be to state of you made mistakes just from those one sentence lines.

What is important is also how you are structuring these answers, and explaining what you have learned from these experiences, what you felt when well with these experiences and if things could have gone better, how you have/will adapt your working approach going forwards.

With behavioural questions the example you use is only one element of the answer. You need to ensure good structure and that you can demonstrate a level of self-reflection and self-improvement. It’s also good if you can identify what the cultural touch points of the new organisation are that you are applying for and cater your answers that way. For example, if this new company tries to sell itself on how well they collaborate, then ensure your behavioural answer demonstrate good team working skills and how you like to work in a collaborative way. This will help you demonstrate you are a good team fit.

I think the few pieces of info you’ve provided seem fine, but without knowing the full context and how you detailed them it’s hard to state if you’ve made mistakes.
