At long last, the awaited comparison gif!

And a still image of the final level for ease-of-viewing:

Wow. Taking these screenshots has really given me a bit of a trip back-in-time! Here you can see the progressive evolution of the helipad, waterfall, and surrounding canyon since the very first inception of RTJP.
The first image from 2009-2011 was made without any prior planning or research - I just made it based on my memory. Back then, I didn't know how to make new models and had little understanding of Trespasser. As such, everything used existing models re-tooled for other purposes - for example, the helipad itself is a stop sign re-textured and with the pole hidden. You can download this level at TresCom if you want to see what I was like when I first started modding.
Next up we have the 2012-2013 incarnation of RTJP, and the first one I began showing off publicly. There are many major errors in detail here due to my heavy use of the seemingly inaccurate JP Legacy Nublar map and very little film reference. This level is just as outdated as the 2011 edition and is nowhere near up to my standards today. Unfortunately I had to take the screenshot of this level in TresEd as the level seems to be broken in some way or another.
Then we come to the 2014-16 RTJP - the one I've been showing off up until now. While I did quite like this level, I slowly came to realize that recreating Nublar in a single Trespasser level was impossible at this scale - the engine simply can't handle it. Additionally, I had to use less detail than I would have liked in order to keep the object count low. Even so, I knew I still could do better. You guys know the story - either way, the level had to be scrapped, which, in the end I believe to be for the better.
So, finally, we come to the never-before-seen waterfall in the final, current version of RTJP (which will appear in the first stage, RTJP~Helipad). As film accurate as I could make it, with a long time spent examining shots of the movie and even overlaying the real terrain, this will be the most accurate Nublar waterfall possible with what I have learned over the years. While there are still a few props missing, this is definitely the representation of the helipad that will appear in the final release!
