By cartoon Saloon and Tom Moore (of the Secret of Kells fame)
I haven't been able to watch it yet as it hasn't come out in Ireland on general release and I can't find it online to my disappointment, so I'll have to make do with the trailer for now. It looks visually very similar to the Secret of Kells with the forced perspective, 2D flattened style. Some of the elements such as the round character heads, the centering of many subjects, and the theme of peering through doors/windows reappear also. The light is also used to great effect in dappling and reflections on water ripples.
