Let me start by saying a Recreation is something you make EXACTLY as it is in real life, no personal preferance, no added "pizzaz" no nothing. If you make a recreation, it had better be exactly as the real coaster is. And something like this would take even an advanced builder several months of photographing the ride to get all the angles of the supports, and several several rides on the coaster, and possibly even acelerometer graphs of the ride to be exact. Now, you can recreate coasters much easier, just that most of them are steel coasters.
For GCI's, they need to be made with something like HSAK/Purgatorium or FVD's, or even Newton 2 when it is released. Real GCI tracks are created using similar tools. Now that doesn't mean you can't handmake the track, it just means that you'll be spending loads of time on the track to get the shapping down.
Now, onto your ride:
Track was VERY pumpy, and rough all over. Support structure really sucked, and didn't look very realistic to Terminator, or even GCI for that matter. Lots of work is needed with the track. Also, theming wise, this was pretty, well, bad. If you do a recreation, at least attempt to make 3Ds. Also, there is only one station, not 2.
Overall, I'd say build GCI's before you attempt to takeon a recreation of this magnitude. Also, I suggest you veer away from recreating rides you haven't ridden on. Dunno if you've ridden Terminator or not, but from the track, it seems like you are not ready to takeon a recreation like this just yet.
Keep at it though. Who knows, one day you might stunn everyone with a near perfect recreation
I give the track a 5.5/10 though.
