Looks impressive so far. (Nice lighting too BTW.)

Wow, Kenneth, you have gotten a very nice ivy-laden trunk. The orangy
lighting is good too. It isn't obvious that the leaves are not connected,
so you're successful there :). I agree with some of the previous postings
that the vines are a little too straight coming up from the ground, but
that's a minor point. Very good work!

BTW:  The tree texture (although not much of it is visible) was made with an
image_map. I took a single photo of a "slice" of real tree bark, made an
alpha channel (in Photoshop) to make the top and bottom of the image fade
to transparency, then applied it nine times up the tree.  The bark is
(obviously) not u-mapped--don't yet know how to do that. :-(  Laziness, I
suppose.  Instead, it's cylindrically-mapped, with each texture segment
being offset in x and z, to line up with the "center" of the tree at that
height. (And rotated about the y-axis randomly, which helps to hide the
repetition.) Also bump-mapped using the same image.

I did that by eye, but it occurs to me that I could use part of my tracing
code as-is to automate the process.

Hey, that's nice!  I can truly appreciate the work you put into that. I'd
like to see more! I especially like the topiary shape. Gives ME some more
ideas.

Sorry, that sounded weird. What I meant was, I took a photo of the tree's
bark, the final image_map being more wide than tall.

I used some area spotlights (to keep the render time lower.)

Glad you like it!

Really cool!  Is this something you could do a time-lapse growth on?  (i.e
different numbers of loops)  If so I'd really like to see an animation of
this.

I keep looking at your vines with envious eyes. ;-)  Just the right
combination of  "angularness" and "curviness." I also see that your vines
sort of move slightly away from the tree surface here and there. Very nice.
My own cylinders do that, but not in any planned way (some do travel
across open space, but some also drill *through* the tree to get to their
next points.) Your images give me inspiration to try and fix that.
