So what i did was that i checked the park size, opened Sketchup, drew a 300 x 75 ft area, and just basically let my mind flow and this is the result. Which i didn't know back then, was the material of the park. The one i draw was meant to be wooden though, so it makes a little difference when it comes to the walls and and the 12ft vertramp.
(i threw some 6ft tall people for a comparison)
