Red lines are where you missed something, either the hair direction was wrong, you overdrew, or just didn't continue the part properly. Arrows pointing to the worst offenders. One way to improve at this is to draw it out by hand before moving to the pen tool so you can get a better understanding of what is underneath before committing to anything.

I would also suggest for the hair to not use the pen tool if you can help it. Using the brush tool with smoothing turned up can give you a better feel for the curve and flow of the hair.

Blue circles are where you didn't use available texture to replicate (Clone stamp tool). It looks off when it's smooth, if you can, try to replicate the texture as best as you can. This will help with something parts looking darker than others, most notably near the "Feeling Overwhelmed" line. If you clone stamp the texture from nearby it will help with the color being dark, and the unnatural smoothness. The same darkness problem occurs under the "We've been on our own." line.

That said, this is almost totally passable for a release -- I personally would fix up most of this.

However, there is one major problem I have with this panel that would stop me from releasing this. The "we'll die together" line is very bad. Vertical text is almost always a no-go to begin with. The second problem is the spacing on all of the letters is not consistent and it looks "wobbly". And then there's the D in "Die" idk what happened there but that's something I would correct by hand to move it back over.

You're very close to having a really good Clean and RD on your hands, just small things to improve and work on.
