That looks OK. A minor point might be to focus, as the Buddha does, on 'experience' and not whether something 'exists' or 'does not exist'. The five aggregates are the sum of experience, and all aspects of experience are not-self, impermanent, and unsatisfactory. The Middle Way of the Buddha transcends notions of 'existence' and 'non-existence' (see SN 12.15 for details).
"Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education." - Ven. Thich Nhat Hanh
"Whether I were to preach in brief, Sāriputta, or whether I were to preach in detail, Sāriputta, or whether I were to preach both in brief or in detail, Sāriputta, rare are those who understand." (A I 333, Sāriputtasutta)
