Great cosplay take, loving the muted palette very much!

"Conceptual Cosplay Design using OC as model" - and it is certainly it's up to your preference if you consider cosplay fanart or not.
You did a very nice job with this and I deeply appreciate the effort you put into rendering the outfit so accurately, but with your own flare.
Also heck yeah on the amazing contrast you have going, especially since many people say red and green is visually off putting as it renders into brow as a combination, but you leaned into that and where able to render and nice Grecian Copper on the figure.
There is a lot more about this that makes me happy but I will leave it at that.
Thank you for making this.

A great game, spawns even more greatness in terms of fanart!

I love the colors and shading on this piece!

"is this even considered a fanart?"
-well yes but actually no.
