Simple and complex
Well, I can always forgive Animation which lacks Complexity if it be paired with a subtle, moving Story, which this and the first Flash of this Series are. The Themes are simple enough - the human Desire to love and be loved - but this is a Theme that pervades a Lot of what we do as a Species and why. Many may undercut this as it stands in Opposition to the Philosophy of 'Each Man an Island', but your Work is much closer to Truth than that sad Strain of Thought. It is a good Work and I would definitely enjoy seeing a third Part, but only if the Theme is expanded further. To make a Sequel for its own Sake would detract from the Collection as a Whole.
