Modding

Hmm, why not open the existing model in 3D, remesh it, make it high-poly, smooth out the angles, draw out the convexities/concavities, etc....

Go ahead and do it, and we'll see if your version will resemble the original in terms of the visual style of the fifth game 😉

I'm saying that artistic style isn't that simple; not everyone can draw as well as WLOP.
