I would like to offer up some hopefully positive and helpful suggestions.
First.
It looks like you are rigging your lines too tightly. You can see this by the slight bow in the main mast. Kits w/ plastic masts and spars are notorious for doing this. Rigging does not need to be so tight that you can pluck it like a guitar string, but just enough to "look" reasonably tight, that is, not sagging. You can get away with much tighter rigging by replacing the masts and spars with wood or brass rod [some go together in two pieces and are hollow in the middle, perfect for reinforcement w/ some brass rod] Plastic gets particularly flimsy when you get to any masts or spars above the top mast. Even lower at smaller scales.
Second.
A good way to ensure that your rat lines come out clean is to first figure out how far apart you want them, then draw horizontal lines on a piece of paper or index card the same distance apart. Place it behind the shrouds and use that as a guide for spacing your rat lines and keeping them level.
There are probably a dozen if not more threads in this forum that go into detail about these things if you want/need more detailed information.
You have not done very much rigging at this point, so going back and loosening a few spots should not be that much work.
Hope this does not sound too critical. I have personally always been very grateful when others here offer up perspectives that have helped me with what I was working on.
That said... I can not wait to see her fully fitted out and afloat. Thats a challenge I am not willing to take on myself.
