Pretty nice, looks like something out of Burnout (cars in that game have no brakes)! You've got a good start to making crashes, and I really wish I had enough vehicles to make a crash this big. I think part of what makes mine look so good is the scale, the size of my cars means a lot more parts that can be removed. My suggestion is to try and remove as little as you can from the cars. Bumpers and lights can come off, but unless a car hits a tree going 80mph, it has more parts that just get twisted then broken off. The best way to give this effect is to take off parts and reattach them at odd angles. Most of the time, you can not attach parts in the way you want so you have to find a way to balance the part where you want it. Most of my wrecks are done this way, and if you even tap the table they are on, the whole thing falls apart. Hope this helps, this is making me think I should write I guide on this.

impressive !

a nice looking town, and morbid as it sounds i love a good accident setup, please check mine out, this a a nice little mashup.

you improved upon your pics, that s good, now, you should consider setting a highier standard for your vehicle fleet, some cars really need work, some text between pics would make for a better story telling, you can move the html blocks of text by pressing enter, they will move down one notch, it will allow you to add text between them, try it, it will flow much better afterwards.

Great job!
