You don't have to draw people - it sounds like something you simply don't enjoy, at least that's what I'm reading between the lines, and if you don't enjoy it it'll be hard to practise it enough and get into the zone when practising.
If you'd like to work on a comic, you could always team up with another artist and do the backgrounds while they draw the characters (a lot of comic artists would love that, backgrounds are hard!) Or just create standalone pieces that you enjoy if you don't care for a comic.
However, I would like to throw in that some of the things you mentioned are just notoriously difficult. I've been drawing faces for 16 years and still have to fix misaligned and crooked eyes a lot of the time. Struggling with something isn't the same as being bad at it - some things are just difficult.
Also, getting all the ugly drawings out until you can create art you're happy with can actually be very rewarding. Some day you look back on your old art and how you started fondly and it's just a really good feeling. (I know I get that feeling when I look at old art where I struggled A LOT more with poses than I do now ... And back then I very much thought I'm just bad at it and that's it.)
So if you do decide to improve your ability to draw people it'll be worth it. You just need to find a way to practise that you enjoy, maybe draw a character you really like a lot, sketch out scenes you thought of, that sort of thing. Something to get your mind off the "am i finally getting it right" part.
But again, you don't have to. This only applies if you WANT to improve your ability to draw people.
Btw, my faces are also asymmetrical af when I don't use the mirror tool (and when I do I add some asymmetry afterwards bc I find it actually looks better and more human that way) and frontal facing faces are just ... Really hard. Again, this is coming from someone who's been drawing faces for 16 years and spent 9 of those years doing almost exclusively realistic portraits. Faces are hard. If you struggle with the things almost every artist struggles with that doesn't mean you're bad or less capable, just that these things are hard.
