Here is the final image which includes the initial sketch that was ultimately used as a reference during the modeling phase...
Charcoals and color pencil were used for the sketch. The modeling, and shading was done in Blender and the textures themselves were created in Adobe Photoshop.
Be sure to search for my name in the next few weeks to see if I have posted anything regarding the project that this study was intended for. Take care all and as always thank you for taking the time to view my work.
