I'm currently testing an AI Upscale solution recommended to me by the great Uschi3. I thought it'd be the opportunity to reintroduce one of my all time favorite piece - Warrior. It didn't do great back when I posted it on Deviantart, but it remains some of my best work in my eyes.
At the time, I was really proud of the visual storytelling this piece provided. I hope it's actually the case.
As for the upscale itself... Well, the original render was 2560x1440 pixels. This one is a mere ten times that! You can zoom on her face and try to imagine what she's seen before getting back through that portal... ;)
EDIT: Added the 25600x14400p version as a downloadable and replace the preview with the normal version. It made my feed incredible slow to load :D
