3/10...
But I've seen much worse
Try to use the engines that correspond to those used in the real rocket. J-2 is basically a frontier. Both are large vacuum engines with a blue plume. The Saturn V is 10m in diameter, 111m tall. You need to clip or bp edit parts to achieve such wide fuel tanks. The CSM is 4m in diameter, your's is 2m. It looks nothing alike the real one. The lander is garbage. No offense, but I think you can agree. I see NO similarity between the real one and your rectangular block of fuel. You
can make a good Saturn V without bp editing, but it just won't be as good as one using it. It is recognizable though. And even if you don't care about 1:1 scale, at least keep proportions in mind. The LM is
smaller than the CSM. You can make a good Saturn V, but it's not something you can do in an hour. In order to make a good replica you usually spend more time researching the proper dimensions/engines than building the rocket itself.
