The worst part for me is finishing, and despite an entire week of effort, it still looks mediocre.
I need to learn how to let go. I sometimes get stuck drawing a certain character pose/facial expression/ whatever and just can't make it look good. I'll draw and re-draw the same thing again and again and again. And it still doesn't work and it's been 2 hours since I started. Failures like these sometimes get to me; I should be able to draw anything I want! So why can't I do this? I feel pressure and it in return makes drawing the thing even harder. It also stops my work flow and eats all the enjoyment I get out of drawing.
I hate it when this happens, especially if its for a client and there's an upcoming deadline and you start to feel rushed but you just can't figure it out and now you can't stop worrying but you need to focus but you can't and now you're super frustrated too and then OOF.
I can draw great feet from memory, but when it comes to hands, I always have to check which side the thumb goes.
My least favorite part is the layout. I prefer not to think and just draw intuitively. But that doesn't work for something that requires a storyboard.
What tabs did for browsers is what folders did for digital art programs. Now I've got a bajillion folders in folders with layers masked ontop of them. Different kind of mess, haha.
Wow, mad props for the traditional inking. I have a friend who's still doing that, and I wonder what wizardry he does to make it all work. I think if you're in the camp of traditional inking, it's best to have someone else do the colouring because it's all hella time consuming (but worth it).
Congrats on the comic projects, I can't say I've ever finished one off myself, haha. I hope you can celebrate that a little before you move on to the next.
Drawing hands and metal things always sucked for me. I am not really a fan of inorganic shapes that require precision and straight lines and hands...well hand are essentially one part of the human body but have the complexity of the ENTIRE human body (with fingers being different limbs and such).
However, that's not really my least favorite part.
My least favorite part is flats. I just...it's soooooooo boring. Inking can be tedious but at least I can experiment line thin and thick lines, adding crosshatching, etc. Flats is just really dull to me. Kinda like waiting at the airport for a flight. You're just there. Stuck. Waiting for the flight so you can actually FEEL like you're gonna get to your destination. I hate the flat process.
I once went to a seminar that talked about the differences between a child and a savant like Kurt Cobain. The point was that there's a place we need find as creatives where we enjoy honing our craft like established artists do, but hold onto the joy we had as children where creating was a form of playing.
I wish I had taken notes, because it was excellent.
Oh wow, this. I kinda have a love-hate relationship with coloring for this exact reason.
I enjoy experimenting with shading and lighting; that's actually really fun for me. But before I can get to that point I have to slog through the unending point-and-click drudgery of doing FLATS...and the longer the comic, the more unbearable it becomes...
Yeah, I remember back when I used to play instruments, I'd often research that sort of stuff (still do sometimes). Read books like "The Art of Learning" and "Mastery" and more on performance and trying to get into that focused state while under pressure, exercise, meditation, therapy, creativity, etc. Idk "creative play" just wasn't a thing for me as a child, so had to learn it the hard way lol.
Have you seen those animation programs that colour in frames with AI? Maybe one day it'll be more intuitive for comic art. 
Yeahhh it's pretty crazy what difference a year will make. When I started just over a year ago I chose trad inking because I felt as though my digital inking was rather mediocre in comparison. But around the halfway-ish point I started gaining more confidence in my digital inking, and even did a short 10 page comic all digitally over the summer which felt pretty good, so now I'm finishing this one out traditionally just to stay consistent but mannnnn am I ready to make the swap LOL
And yess! I'll definitely be celebrating/taking a lengthy break afterwards haha. At 70 pages, this will be the only project of considerable length I've ever finished as well. Feels good... but I'm also very tired 
Yeah, you can cheat landscapes, but buildings are a little more complicated. I guess specialized brushes could maybe help, but it's still a time consumer.
Panel compositions and Bubble locations XC, since I almost exclusively draw comics these have been the bane of my existence since day one, also having to make the perspective grid for all pieces and backgrounds are always such a chore, thank god for kritas one point perspective tool, I swear
