Nice work, you hit the basic learning goals, with some issues on space/time complexity. Check out my comments and let me know if you have any questions.

The space/time complexity is O(log n) if the tree is balanced and O(n) if it's not.

Since you're visiting each node, the time complexity is right, but the space complexity is O(log n) for a balanced tree since the call stack never gets greater than height of the tree.
