Reminds me a lot of the Souls series. Another comment mentioned the jump in contrast, and I don't mind it so much but it conveys an extreme light source. Like he's walking downward and crossing a threshold into a dungeon when there's a full moon in the sky behind him.
Awesome, though I'm not fond of the big jump between the middle and the light colours
Thank you for the feedback, I was a little stuck on how bright to make the lightest colour since it is metal and agree that it is very bright, it didn't look quite as bad on the 50% grey background I pixelled it on but on PJs darker background, it really pops too much so I have reduced the value, thank you for pointing it out.
