Yeah, this is absolutely massive compared to the actual track from GT2! Check the overall length and maybe try some quick builds to see how small it should be.
The real track has a bit of a hill in the middle. Track was very wide but only a little camber in most places. The short apex kinks were very distinctive to this track. Only a couple of long raidius corners.
Hope you will try rebuilding this to scale. It was rarely used in GT 2 and unique to that edition, as far as I know. Was always a thrill when the Event Synthesizer created a race here. 👍
Super touring cards were ideal for it. I'll make a time trial in my Club with your track if it becomes accurate enough.
