Oh my! These are all breath-taking in their own ways! I just want to mention; that I made the same character, which is #3, by the way! I was commissioned to make him too, and it was interesting for me to view the style of somebody else, but on the same character! <3
I also really liked the softness / simplicity of #4, she (or he) looked very delicate and beyond realistic.
You did beautifully~
Can't wait to see more from you!
