Help with finding some official artworks/renders for a crafting-project, please!

Hello!

I'm writing this in the hope that someone whos more skilled in finding artworks etc. than I am might be able to help me out here!

To give a little context and details what I'm looking for and why, here is a little introduction: Besides playing video games and especially FFXIV, I basically have one other hobby, which is cross stitching. Over the years I've done a great many pieces in relation to the Final Fantasy series in general (if you want, you can have a look here: https://www.deviantart.com/melian-vidumavi ).
My last "big" project that has yet to be finished is a patchwork-blanket with all FFX-Aeons on it. I finished the stitching, the blanket still has to be made. But since the stitching is done, I need a new project to work on and I choose to start working on a second blanket, this time with FFXIV as subject!
My plan is to stitch portraits of the 6 leaders of our 6 "city-states", aswell as their emblems.

Now, why do I need help?
Well, I'm using a computer-program to turn pictures into cross-stitch-patterns. So, for that I obviously need pictures.
And those seem to be more difficult to find than I expected... til now google search and the final fantasy wikis have served me well, but this time I'm a bit at a loss, so I'm hoping someone might be able to help me out!

What am I looking for exactly?
I made it a rule for myself to only use official artwork by SE, so fanart wont do for me! Sorry, I know theres great stuff out there, but I really only want to make use of the official art!
The optimal thing to work with for me would be render-artwork, aka pictures with no background (so screenshots dont work to well). Since I want them to all look the same (stylewise) and as close to the game as possible, character-renders would als be prefered over concept-art! The higher the resolution, the better obviously! (Specially because I wanna do portraits, so theres a good chance that 90% of the picture will just get cut)
As mentioned above I wanna stitch the 6 "leaders" so I'm looking for artwork of:
Nanamo
Merlwyb
Kan-E-Senna
Raubahn
Aymeric
Hien

...sorry for the novel - thanks for reading and thanks for any help in advance! Keeping my fingers crossed for someone with a secret source of pictures that I dont know about!

Have you checked creativeuncut.com? they have a huge collection of ff14 renders in pretty good resolution like this one : Aymeric
I haven't browsed all of their ff14 galleries so can't tell if all the characters you need are up there though.

Thanks for the advice! I checked and sadly I still couldnt find any high-res renders of the 4 original leaders from ARR - I did some digging of my own today and found something that might work, but I have to admit to being a bit... shocked on how difficult, almost impossible it is to find high resolution renders and artworks of such important characters. I had better luck with any character who appeared in Dissidia...
