Biog Living Spaceship

Very early days, as i really should finish other projects so please don't expect and update soon, but i've started on the Living Spaceship from the revamped Dan Dare in Prog 1 of 2000AD.
I'm doing it to match the bust and Living Axe that i've already made and i fancy going the bio-organic route again.
So where am i?
Basic shape of the body, mushroom thingy, engine tubes and a few tendrils crudely blocked out using crude air-drying clay.
Next step, when i get round to it - refine the shapes more by taking away in some places and building up in others.
