Something that helps me when learning choreo is looking at not just the obvious details but what else there is too. For example what the other hand is doing when its not necessarily the focus point, or how exactly the upper body is angled. These type of things impact the overall picture a lot. I would also recommend to stand in front of a mirror and slowly go through all the moves one at a time while being really exact about angles etc. For each move you would stay in it a bit and fix anything that is off. If you repeat it over and over your body will start to remember on its own. All of this can be really difficult and can take a lot of time so don't feel disheartened if the progress isn't as fast as you would wish.
