Glad you came back. It's worth it to continue growing with all these other amazing artists.
Regarding your last drawings I would suggest to practice a bit more basic solid forms.
Your stuff is very loose (which isn't bad!), but try to develop one of these loose drawings more.
Make a loose gesture like drawing, as your used to, and then try to make a solid line art out of it where you could build a whole painting upon.
Keep on growing Christina!
