I find this work very interesting because although you ask me to see the branches, I see more of that fish eye, or all-seeing fish eye. Although I must recognize that the detail of the branches inside the eye is perfect, a work of height. A science fiction drawing! A round of applause for you, @opheliafu.
I see a face inside the eye- the way that the branches cross over to create eyes and a mouth. The face looks ethereal.
