Indentation seems like a little thing, but early on a lot of new developers struggle with it and can get into bad habits. Your indentation is great (other than the minor tab size discrepancy, but that's an easy fix). Very consistent and no wasted space. It's a small part of programming, practically non-existent in the minds of senior developers, but to get into good habits like you're setting now is excellent.
