An unexpected plot twist to say the least!
You had a terrific story concept (can never go wrong with anything noirish), and I loved the moody feel from the very beginning.
While there were points in the animation that were a little awkward, like the part when he poured himself a drink, or when he was recalling his childhood, there were parts that, can I say, outshone them? Especially what lay in deeper part of the sewers.
It's the eyes that really haunted the viewer.
And that voice!
Equal parts gritty, bitter, and urban, raspy and deep, and hungry.
Loved it!
