Just keep doing what your doing.
It's looking good so far, when I started about 6 years ago I would come home from school and say to myself, "right, I'm going to get on and off 4 pallets tonight" set a goal and practice practice practice, if you nail it only once or twice its easy to forget or get wrong. Nail it 30 times so you could do it with your eyes closed. you will progress easily that way. Its looking quite tidy already though like Carl said, just loosen up a little.
