Ugh. This looks like hot garbage.
Nothing physically wrong with the setup or the puppet, but the puppeteering is dreadful.
All that random movement, with no regard to where the creature is supposed to be looking or what it's supposed to be doing means that there's no effective illusion of life. I realize that manipulating this thing is probably difficult, but less would be so much more.
This is a performance artform, and when it's done properly, the effect can be sublime.
When it's done like this, not so much.
