To start with, please go to this link and open all the boxes under Staking and Guying trees.  Your staking is too low and it looks like the tree is not able to sway somewhat.  Trees need to be able to move some to develop the side roots that stabilize the tree.  Otherwise, once the staking is removed, the tree is not stabilized and will fall over with a strong wind.  https://extension.umn.edu/planting-and-growing-guides/staking-and-guying-trees   Secondly, your maple should be pruned for form now while it is young.  A good branch attachment is shaped like a U.  Branches attached in a V shape will tear off as the get larger and heavier.  Don't worry about the top, it will straighten out as long as there is sun.  https://extension.umn.edu/planting-and-growing-guides/pruning-trees-and-shrubs   It would be good to open all the drop down areas to familiarize yourself with care of your tree.
