Came out really well with similar colours but not quite the same and I had to adjust the layer height to get it similar to your image
Black to 8
Red to 18
Silk Lime to 30
White the rest
printed on X1C, used orange instead of red but didn't come out as nice as the OP's one did, maybe my filaments are old (Prima Value PLA), the photo (cover) where it really looks nice was scanned in 1200dpi bed scanner, the rest just photo on phone, the “scanned” one WOW looks really nice, then again, from a few feet away it does look nice (this is my first HF experience), thanks OP for the design though
