Although a reflection this needs to be supported with relevant theory and literature: e.g. leadership and management theory, change theory, communication, team working, current health and social care policy. What is Critical analysis? discussing the strengths and weaknesses of the literature you use as you apply it to your own group experience. Critical writing involves constructing an argument/debate about the subject you are discussing. Focusing on certain areas may help you write e.g. communication, leadership, team working - it's your choice. You can use a model to reflect but this is not necessary.
