>>1989589>how do I get rid of thosecouple of ways:
simplest is to just delete or reshape the part underneath. This is where layers, moving objects "up" and "down" comes into play to get to the one you want to work on and then moving it to the back.
Another is you can simply move the nodes slightly of the top object to cover what would otherwise leave a slight outline.
For parts where the same object is both over and under another an easy fix is to dupe it, move the dupe to back, then delete parts of the top one to not have the bits that go under.
Or, if the parts over and under are well defined as they are here (with the neck anyway) I would do it like in pic.
On an unrelated note, I thought the image was some fan-art of Matoi Ryuko as a demon snow princess or something
