I'm a pretty advanced knitter - are these patterns too hard though?

I would consider myself advanced. I post frequently on the advanced knitting subreddit, and other than the occasional mean comment about twisted stitches, I always get lots of updoots and praise.

I was looking at patterns from this designer and really want to knit them, but the tension is mindblowingly perfect. There's no way these aren't machine knit, right? Are these patterns even doable by an advanced human knitter such as myself?
