This is a bit short and simple, and needs to be expanded if it is going to get accepted. I also can't quite figure out why you've blocked of the loops the way you have. I'd also advice you to hide the breakable lines under the normal lines. (If you find it difficult matching the curves you've already created then you can copy the normal lines you already have by moving them whilst holding down ctrl on your keyboard, and then place the copies on top.)
