I would try to start of strong by using the two quarter pipes at the beginning. You can go back up the ramp to use them several times. Then grind away and link with kick trips and manuals. Also find out what your characters special grind is. You can easily rack up 7,000pt X whatever ampunt of tricks you link together. This can be done in on good combo.
Set your char up with a special manual and 2 special grinds. Start on the rail to the left before you smash through the glass, trick your way to the box of plants (plenty of room for the special manual), do your special grind on the plant box, manual to the ledge left of the yellow car, see how far you can get over the light railings and do a big stunt down the disabled escalator. Or something. --- We aren't people, we're text.
