This is my first time posting (besides my participation in this year’s sculpt-off)!
I started this pumpkin as a sketching exercise for a Zbrush class I was teaching at FutureGames, I created a bunch of thumbnails and did a quick instagram poll and refined one of the most voted ones, the color is mainly done using polypaint, added some additional details and maps with Substance 3D Painter. Rendered in Blender. I recorded the whole process
