Hi @drhira!
It takes a bit of imagination to see a tree in your drawing. Rather it could be a tendon or muscle or a nerve or neuronal terminal.
On the other hand, your work includes digital manipulation, which is not allowed in this challenge (read the bases).
Your drawing process is a complete disorder...I don't know what to consider as the final result. Please, some respect, you are far from being a "little bit artist".
