I'm not sure what I'm doing wrong,
The sculpting tools in Blender gives me so many issues.
Especially with anything meant to be thin..... like the end of tails, claws, teeth, tongue, fingers, toes, etc....

This is the old raptor model I've made over a year ago,
I decided to retouch it but it ended up fucking up some of the geometry.

After failing to repair it, I left it as is and did a quick little rig on it.
