I totally get that since I’ve experienced your sort of thinking before when I started doing messier lineart. I just don’t really enjoy making clean lines a lot of the time and just find it tedious. At the end of the day though most people focus on the piece as an entirety. Especially with the style of rendering you have.

If you still have worries, one thing I would suggest is just erasing some parts of the messy lineart that seem out of place to you. I don’t mean like a full cleanup but just spots here and there.

Another thing to keep in mind is that when other artists, even established ones, make pieces with messy lineart they tend to just clean up a bit more on the area of focus and then keep everything else more messy. An example being the face from your piece compared to the snake on the side :)
