I like the idea of alternative griffin concepts. I call this a Pit Griffin. They were bred for fighting in the pits and eventually became naturally featherless/hairless save for a few blood feather-like structures. They are wildly aggressive and monstrously dangerous, though they have lost the ability for flight. The large spur talons on the wrists are venomous, however pit griffins are immune to the venom and instead act as very dangerous weapons. I took a lot of inspiration from the awesome artist Carlo-Arellano.

In the future, if you want artwork from an artist, try to see if they have commission information listed in a journal. If they dont, send them a note and ask. These are real people spending real hours to create content and asking them to do that without any for of reimbursement belittles artists as a whole.
