I like to think CGC classes are a little more relaxed than school. Excuses are more understandable here. Like when I admit that I didn’t have enough time to finish retopology either.…🙃
Your neutralization looks good and the orb retopo is well on it’s way. There’s a bit of edge sliding that could even the faces sizes out a bit better. Here’s an image outlining where differing edge lengths could be evened:

Where the green edges are good and consistent, but the red aren’t. Same for blue/yellow. It may seem small and insignificant, but especially since the orb is a round shape, roundness depends on evenness.
Still it’s minor notes. Overall you’re doing great 👍
