This was done for a good friend of mine. He wanted me to do a sketch of his snake form inflated to a massive size. I added the tail coiling around the belly and the little guy on top. This one came out fantastic
I used Blender and a few models mixed together for reference for this image.

(i some how managed to forget his fa name...)

(I did do a render for tyr at the start of the year... but I've temporally lost the source files... I will post when i find them o3o.)
