On the Banks of the Hyaur

Hello....

So in this image I wanted to create a riverside ecosystem. The pillars (created with xfrog) are the mansions of an industrious insect, and for the most part they are all connected within the river banks. The other flora is composed of trunks and spiky protrusions, around which there is a fleshy meat that many creatures consider a delicacy (if they can get to it). But beware the spikes, upon which are much smaller, poisonous needles not seen by the naked eye.

Well, thanks for looking!
