I originally chaged the eyes color of some Toa for the reasons that you and @Stuubh mentioned. I went for Blouks and the original blue eyes go a bit unnoticed. I also wanted to each have a unique color.
But I had to reverse them to the original eyes colors not to be disqualified. Now, this really is a quick change, at least for me, and I wouldn’t mind if that rule was removed.
The thing about the comic comparison is that we have multiple depictions of those characters. We know the correct eye color, even if the one shown in the comics is wrong. You know Vakama’s eyes are the wrong color because we have a set, and numerous depictions, of him with the correct color.
For the Hagah, though, this is it. We’re only going to get this one depiction of them. Whatever eye color they have in that image will be the one they canonically have.
On the other hand:
Obviously, I can’t speak for all moccists, but for me personally, I agree that eye color isn’t a huge deal. Often, I give my mocs whatever eye color I have, and if they have a Metru head I don’t even bother with an eyestalk at all. (The only exception is that I try to stick to Ice Characters having blue eyes, and even that I don’t hold to all the time). So I think changing eye color for the art should be fine.
Anybody knows when the official deadline is, I am still allowed to make some changes to my entry?
The deadline apear at the bottom of this topic, october 2nd if I’m not wrong.
Since your entry is already acepted in the contest, my recomendtion is to ask to the mods if they allow you to upload a new version. If doesn’t change nothing that could imply a disqualification, I belive you should be fine.
You are allowed to make changes, but only once.
My Entry in to the Hagah Art Contest
You should post it here:
Ok thanks
Best of luck to all the entries for the art contest this weekend 
Wait, sorry, just to clarify- the deadline is this Saturday October 2nd? And if so, does that mean entries can be submitted ON Saturday, or do they have to be submitted before (e.g. on or before Friday)?
And if they can be submitted on Saturday, what time of day must they be submitted by? Will entries submitted at 11:59 PM be accepted, or do they have to be submitted before then? And what time zone applies? (Eastern Time, Pacific Time, etc?)
(Asking because I’m finishing an entry and gauging how much time I have to refine it).
You have until 11:59 PM EST on October 2nd, 2021.
Entries can be submitted on Saturday. I don’t know what the ruling is on down-to-the-second entries, but I wouldn’t recommend that you let it get that close.
I created an alternate build to stabilize Pouks’ shoulder armor:
I substituted the blue 43093 piece with 18651 to prevent the thin bracket falling off when you remove the shoulder armor piece.
The brackets stay in one place and minimizes shoulder armor wobbling. Hope you find success with this build approach! 
I’m like 30 hours into the artwork and I just realized i drew Pouks with upside down lower arms.
Oof
I look forward to seeing your artwork if/when you finish it
Just one day left!
I think I can make it, it’s due 11:59 saturday night, right?
Eastern Time, yes.
Fingers crossed they don’t extend the deadline again. I’m eager to finalize my Mocs
Seems highly unlikely theyd do that
Today’s the day, I wonder how many last minute entries will show up?
My guess is 2
Edit: I was wrong. We got, like, 8
