I plan to redraw/edit the first 20ish pages of West for printing. This is to create a more uniform style, invite new readers to pick it up from the get go, and give older readers something fresh to look at. However, I really like the idea of keeping the original version of the comic online for people to see. To me, those messy transitions were a necessary and valuable part of the creating process, not something I (or anyone) should be ashamed of. That said, there is value for both readers and artists in investing in a story that has it's identity and 'look' firmly nailed down. It's simply more professional and if I want to West to be taken seriously I need to start with the basics.
That's my stance on redrawing, but as far as actually doing it goes I'm reluctant to get mired down in anything that delays the progress of the story. This comic is going to take years to complete and while that's fine with me, I'm also keenly aware that anything can happen at any time so delays (like redraws) are something I could do without. More over, my current interest in making a living from comics is low enough that I'm happy to let the comic cultivate a following by itself, speaking for itself, exactly the way it is. For me there's no need for recognition and professional success at this time, just an urgency to deliver, though there's certainly nothing wrong with wanting both.
Improvements can always be made, but what those improvements are depends largely on your priorities and what you want, so have a think about that.
If your want to improve your following consider whether it's the quality of the early pages or simply moving on with the story that will help more. If it's been a year and you feel the story is at a point where events alone will draw people in, maybe hold off the redrawing for quiet period. If it's been a year and you feel it's the style of the art that's winning people over, rather than current plot, then yeah maybe a redraw is in order.
