I have posted this in the sandbox, but i think that should not really be the right place to post it. It should have been here.
In any case,I would like to ask if anyone knows how to refine the vector: See Images below , esp on the red circled parts.
The main flaw i wanna pick out is, the way it is shaded and blended.

Any help would be appreciated. Thanks in advance.
