Here is my knight model! I had a lot of trouble with this one, especially with clipping on the mirror. Once I had a handle on the clipping, I progressed really quickly on the face/hair though.
I’m still not sure if I’m entirely happy with the face, but it’s something I could spend hours on just fiddling with vertices and I need to move on!

Trying to make my from this reference and cut it down to low-poly proved to be a challenge but I think I did okay in the end. It was tempting to make it high poly and try my hand at sculpting though!
