To find out for sure put your hand in the entrance.

That said you could also try this.
My ball will come check out what is going on anytime I move around in her cage. She does the same thing your pics show but she has never tagged me, or tried. But I have never tried my above advise. I pick up the hide and let her see its me, then pick her up without issue.

I really doubt your ball is wanting to strike you, not saying it never will. My GTP will usually come check me out when his glass slides open and every once in awhile he decides to see how I taste. Its part of the hobby. If you handle enough snakes one is eventually gonna pop your cherry.

I have some super gory pics of a GTP bite on my profile. Don't show them to children!
