i changed the bridge to road,because rule said need busy street.so i think make road and put city building side of road is better than bridge
i made final design now
hope you like it
i parted model to 4 part model,1st layer is for city,2nd layer for road,3rd layer for eggs,4th layer for car and people etc.then rendering each part model,and then merge all to one for rendering,or use photoshop merge all layer.don't sure now,maybe photoshop is easy and good
C&C welcome
