Thanks for the comment in WIP. I decided to keep the model the same (no beefing up), but displayed it a little better this time. I think some people were fooled by the poor composition of the WIP into thinking that the head was proportionally huge. I also tweaked the tree model so the main branches branched more smoothly. Redid the grass with RipSting’s excellent Fiber plugin (33MB .blend file!). Post was done in Photoshop.
