Tractus Cephalopod

I drew this alien for my Anatomy & Physiology honors class. It is a hybrid of an animal, a plant, a fungus, and a parasite. This is one of the first non-still life ictures i've ever done with some skill, and i still hate it so if you have any pointers, PLEASE TELL ME!!! and please don't steal this from me, I don't care if you want to make a better drawn version of it but just mention me and don't say that you came up with the whole thing, or i will find you.
