Hey there. I must have missed the section that handles encrypting the session key, my bad.
It's more the struct method of embedding though that I was emphasizing. Structured encrypted data has high entropy which can give away it's presence. Try running some of your before and after images through aperisolve or the cyberchef entropy analysis tool and see how the analysis changes.
