Quite nice ent! The image is a little strange looking though, I think that the ent's textures are too crisp in contrast to the background.
I wonder if more explaination on the background is possible. All procedural, that is amazing(hypervoxels?). So were all the textures done in aura then? Composited in aura too? I think that is the limit of aura here, or am I missing something? The ent is a model isn't it?
wizcracker does aura dv come with any type of manual, maybe a pdf? That is were i have gotten all my aura knowledge. Most of the tutorials(small handful) are focused on editing animations, and admittedly i hevent done much there. The aura manual is very comprehensive imho covers the tools very well with good examples.
