You're definitely on to something here, Cedric. Those with an urban eye recognize the precast portable concrete barricade sections and their scale. The bright red, apparently plastic, piece in the background threw me, as it really does resemble a piece from a child's toy set. The blurring, to a photographer, suggests a lens tilt which throws the whole perception of scale off-center.
In viewing the image for the first second or two here is what went through my doggy brain, for what it may be worth to the artist.
1. Is that a Lego piece back there?
2. No, it can't be. THose are concrete barricades.
3. But it looks like he's manipulated visual scale and plopped a toy piece back there into the image.
4. No, it's not a toy piece. It looks like a section from some kind of European-style barricade system with interlocking pieces.
I wonder if there's a perspective that would make this a purer and more mystifying image? The zebra stripes are a nice feature, too.
