Nice updates, loving the 3d tree, welldone on that! I feel your last render of it in the scene seems a bit bright.
Nice creature, why doesnt the front leg / tendril have a rimlight? You could also add a slightly darker value with an overlay layer on the the head part just to round it out a bit more, just a dab with a soft brush, it feels a little flat. Good job on the fleshy colours.
Keep it coming!
