Leave them! I think they look perfectly fine. Your colourwork is sharp as hell, by the way. Those backgrounds are shockingly good. Everyone has a few fishy pages at the start of their comic, but you gotta keep moving imo.
Don't be the comic ouroboros forever redoing your first 5, 10, 20 pages, you're gonna be the only person who ever really sees those mistakes. You can go back once you're done and redo them if you hate them that much, but otherwise you'll learn more pushing forwards and keeping these past errors in mind rather than on your canvas. Having a finished comic, for many readers, is more important than a perfect one.
I always go back and kick myself when I see the first ten, fifteen pages of my comic, but I have to restrain myself from redoing them or I'll never stop! Better to use all that improvement on the next project than stalling on the current!
(However if you really really really hate 'em to the point where you can't post please ignore me and tweak it around - your enjoyment as the artist is the most important thing! Good luck!)
