Dcurrie, even being very green to this art I would call this a masterpiece as is. I’ve been a industrial painter for 10 years and “over processing” your work is almost always a mistake, its hard sometimes but “put the paint gun/Graver down and walk away”.I made some changes in Procreate. Better?
If I could point out one thing, its that cheetahs have a thin line of dark fur that starts at the eyebrows outlining the muzzle and stops at the corner of the lip. Your cheetahs muzzle looks more that that of heavier big cats like tigers. But aside from that it is truly a wonderful piece of work.
