Thanks everybody!
I agree that the fountain is very MDF-y, I saw it and thought it would fit it's purpose as a bit of a side-scenery piece. Hopefully when surrounded by chairs, planters and various scatter terrain it'll blend in a bit more.

I'll be putting the finishing touches on my Police Officers and Swat unit tonight so I'll upload the pictures of those as well as local street "business lady".
As for the list of the above items here we go;
The Fountain, Street Stalls and Garage are from the TTCombat range of TheTrollTrader.
The Police AI Drone is a bendy plastic Gundam MS Frontier 1 Gashapon Figure. I've got another 2 of these in different poses which are almost complete.
The Civilian Cars are Norev 1/43 Peugeot 4002 Concept Car. (I personally prefer 1/43 scale cars, while the plastic military vehicle kits look out of scale, the smaller civilian stuff seems to fit nicely - I'll see about getting some pictures next to miniatures later.)
GSDA APC is an Old Crow APC, I've got the turret for it nearly complete too.
The Police Interceptor is a Mondo Motors Lamborghini Reventon 1/43 Scale, decals, sirens and a bit of blue paint added.
The Maintenance Vehicles I have no idea. It was purchased from a Bring and Buy.

Police APC is (I believe) from Westwind's Secrets of the Third Reich range.
The Hummer is a repainted Victoria US Hummer Army Ambulance 1/43.
The Government Special Forces are mostly Hasslefree Miniatures with headswaps and greenstuff apart from the cyborg-guy on the left. He's the limited edition Infinity Bounty Hunter miniature with a slight head conversion.
Phew!
