Stuck and in need of critique or paintover

[dremorai]

I was excited about this when I started it back in the beginning of March, but I knew from the get go this was going to really push my artistic abilities. Now, I open it maybe once a week, do what I can for half of an hour, and then feel unsure of how to fix and finish the piece. I don't want to drop it completely as I'm honestly really proud of it as it is, but I need some help getting it to the finish line.

Any critique, redline, paintover, etc is welcome!
