From your pics, how much of the hard structure is showing? If what we can see represents a large part of it, you may want to add much more in the areas yet to fill.
For example, where we can see that black thing with the tentacles, if that's the only one, I'd try to add 5-10 more in just that area alone.
Excerpt from Robert Crais' "The Monkey's Raincoat:" "She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
