You have 2 big things going against you - your age (low hormone levels) and your height.
Yet you put on a great amount of mass in such a short time span! You are definetely doing things correctly.
Overall, your body is pretty balanced, apart from chest which needs more thickness to be in proportion, but it will be fine when more mass is added. Just keep doing what you are doing and add more mass. There's nothing else to worry about right now.
