model made by me with cinema 4d
you can download free and use my model for your creation
in exchange for naming me in the description
to round off the shapes you should use the subdivision surface effect
and for the cape in addition to the subdivision effect you should use the fabric surface effect
to see the final result with these effects you can see it on my arstation and my instagram
