Hi! It would help if you marked the issue on your screenshot so it's clear to what part you're referring to.

At first glance, it looks like the UVs could use some straightening to minimise aliasing artifacts at the seams.

Generally one could attempt to put the seams in places where they are less prominent.

Share a troublesome part (high + low), to allow reproduction of the situation.
