Replying to Urban drop in.

So to start, I already have a 5 ft drop in, with a rectangle for the base, and a flat section for the drop in with ladder steps to come up with astro turf on them to go down. Sounds good, if you really want reference you can check out my salomon summer edit.

Anyway, I'm trying to turn out into something like Andy Parry's drop in in TC EP 2. For those  who haven't seen it, basically its a maybe 10ish ft drop in into a flat platform maybe 3-4 ft off the ground which leads into a urban style rail. I've built the new rail, I was just wondering who's done something like this before, and some tips on how to convert my setup into a summer drop in for a urban style rail. Thanks guys.
