I don't know about the last review - I personally loved the strings. The short attack on them almost suggests something like an accordion or possibly harmonica - but it works either way. I think it adds just the right amount of surrealism and interest. Don't change a thing about the strings.
I really liked the concrete percussion towards the end but I wasn't crazy about the police sirens - just an opinion though. I thought it would still give the impression that you were after even better without them. Perhaps better still would have been a couple of ever so slightly detuned air-raid sirens in place of the law enforcement/emergency vehicle. Still - just an opinion and I respect your decision to do it the way that you did.
Great melody and accompaniment - chord progression was really damn nice.
