No, it isn't close yet.
For this challenge I tend to expect a minimum of plus or minus 0.25 meter accuracy, more depending on the size of the thing in question.
Edited this part in bold from 0.5m to 0.25m, I misspoke there.
What was wrong with it again?
Well, it's small...
You used 12 wide fuel tanks for the first stage, these are 6m wide. Saturn V's first stage was actually 10m wide.
Based upon that, your Saturn V is about 1:1.7 scale, so much smaller than it should be.
I have no issue with people making smaller-than-real-size replicas in general, they're equally valid representations. But for this specific challenge, the task is a
full size replica.
Which is very ambitious indeed for a Saturn V.
I'd recommend a different rocket, Saturn V poses o challenge due to its size, and in particular an Apollo recreation must have a reasonably accurate crew service module and lunar lander.
The attached picture shows what the scale is in SFS.
