I can't really tell where your head will be when you're in riding position, but from your post # 43, it looks like the front of your helmet is just about in line with a vertical line at the back of the front wheel. Are you sure your bodywork is not going to enclose part of your head, which is not permitted? And the further back you position your body and head, the less peripheral vision you will have which can get confusing at speed. Otherwise, it looks like you've nailed the perfect shape so far.
