If I was really to think about it, even re-read FQ in its entirety, that would be a long list.
There were generic things and specific things, and things that were not even really in-comic.art style
Try to have something more reminiscent of the old main quest / original quest art style. Lines and also colours.
The digital colouring may be more vibrant, but then you have that nasty RGB -> CMYK transition and CMYK is one of the worst colour spaces. Looks like a swamp on November afternoon. communication
The old scrolls of color would be back. No more FB.
No plain rejection of criticism. (Public) Art is always a dialogue, no matter what. If you paint something on a wall, there will be reactions. Different perceptions, different reactions. Accept that as normal.
And sometimes citique is not subjective, it's rather objective, factual. That could be a hint how to improve certain aspects.in-story / in-comic generic
Keep focus on the rich set of characters (with depth) that we already have.
Do not introduce many more characters - especially when they remain shallow. Do not introduce new characters just a dress-up dolls for fancy costumes.
Re-tell FQ with more time, relaxed writing, no sudden jumps (like in some Japanes movies, where you're supposed to complement the rest), no rushing, more character-character dialogues.
And give certain things & characters more screentime.
Paint people more-dimensional, not too plain evil / good.
More depth to characters.
Less holes in the story.
What most people already wrote: Explain him. Currently I wonder what his task is, besides being another figure that remains rather shallow, no matter how mysterious he is.Ember / Teir
For several years of comics we were told that both are close, and eventually they recognized later in FQ (which is also a good time ago now). Still, Ember pushes all the thoughts of cubs away, because she's so totally busy being a chief of the tribe and stuff. Makes me wonder how Cutter could have her (and Sunstream). He was also chief on a quest. And totally busy and stuff.
Oh, and don't make Teir be his own grandfather. Yeah, I know it's different, but seriously, ... they could have left his father a mystery or just some other elf (after they introduced 1000s of characters), now there's something like a huge elfin incest and everyone is anyone's brother, sister and grandparents at the same time... (exaggerated but you get the direction)Cutter
Again: His end was flimsy storytelling because of the off-EQ-world / off-comic reason "we're exhausted, we need to end the series, ah, let's kill the main character, then every series must end". No matter what. The bite itself, well, okay, why not? Doesn't need all that heroic stuff all the time. But that nobody really cared, that he, for himself, didn't care, no use of preservers, other possible healers and so on. And please, not Skywise complaining about "unspent time with each other" - when he just had left with the palace for good.
I think the series could have ended without him dying.
And maybe save him that Tim-Tam.Strongbow / Moonshade
That there is a conflict within this old couple after so much time... well, yes. But somehow the whole outcome and "solution"... meh.Kahvi's relations
I wish there had been more talk between all her relatives. She was in the furs with everyone and is everyone's mother. So lovers and children have a common part, something to talk about, to exchange news and views about her.
More screentime for that.Two-Edge
Was there something in for him in the end? Tending more to his troll or the elfin side? Get to kick his "mother's" butt? Something? Winnie
Add more depth. More reason. More history. Explain why, make it more understandable.
Less of the "pure evil for no other reason than the off-world reason that you need an anti-part". Less of the Disney-style-evil-Queen.Rayek
Now let's get to the big Kahoona, right?
God bless fan fiction. God bless fan art. We can do there what is good and right and cancel all that Rogue's Curse.
To me R's Curse felt more like the idea of someone who had a sudden idée fixe about some dark, slightly exotic gunslinger-wild-west-comic-crossover-hispanic-touch-tragic-lover thing. But it does not really feel ElfQuest (which is also partially due to the different art style).
So let's all just assume it is not canon.
And let's forget this silly thing, that re-set, reversed his whole character with that "No, can't let her go, she must love me back first."
I think we already discussed that at length, but still, it was one of the worst points ever in EQ, also on a meta-level, m'kay?
To stay with Leetah to raise "Cutlet", as Manga suggested, would have been okay, too (if Cutter really was to die). On the other hand, well, probably it would not have been easy with Winnie still being spooky.
I think if Venka wasn't his daughter she'd have been a fairly good choice as a lifemate for him.
Korafay... oh, well. Hehe. Would be a similar level like recognizing ShenShen. Much contrast. Probably sparks.
There are plenty more characters, if I think about it. A good bunch of open things, loose threads.
