Thanos Bust for a Class I am in.

Looks like a solid sculpt. I like the style, but doesn't Thanos wear some sort of armour/crown?

Hey does. I just wanted to sculpt him without.

I think your skin is showing as a little too pink and light (too human) for Thanos.

Nice work, but there are a few things killing the likeness for me.
His eyebrows seem far too high and arched, and his cheeks too gaunt. He also looks a bit malnourished.. despite being a monstrous purple titan, the guy usually looks very healthy with very full features. I would push in the crevices in his chin more, perhaps inflating the areas in between some.

Here's some ref:


I also think the anatomy could use tweaking on the upper torso, and I think it would look a little cleaner if the bust were cut off in straight lines rather than more organically follow the anatomy.

Also, I agree with ScoobyDoofus, his skin is too light.
