Great work 🙂
If I was to change anything , I would sculpt his head – firstly to add some imperfection to the overall shape as it is too perfect to be believable , and secondly , to make it look as if the carrot, eyes and especially the chilli mouth look like they have been “pushed” into the snowman as you would if you were making it in real life. At the moment, the chilli looks to be magically floating on his face.
In CG , beleivability and story play a huge part in the appeal of a piece. Try to stray away from that CG perfection and mess things up a bit because nothing is perfect in the real world.
It would be great to see it textured in a sunny winter scene 🙂
Keep up the good work!
