Hi Everyone
I followed the advice noted above by @KeithRJ and @Stenis and from the guidance shown in the attached video.
AI Masks in DxO PhotoLab 9 — 3 Examples & Advanced Masking Techniques
Avoiding the presets and just hovering the AI selection over the cheetah to select it followed by a negative mask to refine some edges I managed to get a really good selection and turned an average photo into something I really like. Attached is the before (just crop added) and after with the adjustments made.
Thank you for the help and hope others learn from this as well. Now to tackle the leopard
