Vision: It reflects a fantasy world that lies side by side with our own. I really enjoy that. The people have no idea that they are not alone at the bus stop. You could have gone further with the decrepitness: perhaps the cobbles under the creatures could have been broken / worn and stood out amongst the new.
Originality: Love the idea; love the look.
Technique: The colors are so light and delicate, as are the strokes. I like the shimmery quality of the people.
Impact: Love it, but would have been interesting to have the creatures stare at the viewer.
