Character Progress - Zhul'Thun

This semester, I have been working in Vaugn's Character and Hero Prop Modeling class on the tree character  that is included in my thesis: Zhul'Thun  
Most tree characters that can be found through a simple search resemble Ents (from Tolkien's fantasy world), but I want to try and make my own fantasy-inspired character that has it's own aesthetic.  This was my workflow:


Due to time constraints and necessity to begin modeling the character at the beginning of the course, I did a quick silhouette.

This was the result, in which I then continued concepting in Zbrush.  Though I'm pretty happy with the result of the silhouette, I don't think I will do this method again - I am more powerful as modeler when I have a full concept to work from.  I found myself struggling with some shapes/areas of the model.


This is the result I have now.  I should be finished modeling by this Friday, where I will then Retopo (attempt Zremesher), then begin UVing and texturing.
