I'm trying to find it, but I don't see the stray line either : /

If you want to get really technical, the designs on her arms, and breasts are not even.

On her right arm, the black design is higher up than on the left arm.

and on the breasts, the middle spikes are not the same.

But that's getting really picky.

I wonder how this would look if you took the coloring to the next level.

Blending everything real smooth, so it looks like an oil painting. If you do it well enough, you don't even need the ink lines.

Here is the uncolored drawing, for those who care:

Whoops, that's my bad Jax. You see where her leotard ends at her crotch. That's sky below there right? I totally blended the two together therefore making her pelvis look way longer than it really is.

I recant the previous comment.

THat's wicked. Bottom lip is a bit massive, but what the hey. Well done you.
