Nice work! I can tell you have a lot of time and tools invested there. I still have my leather carving tools and stamps but haven't done it in years and years. Oh I make the occasional thing out of leather but only rarely is it tooling leather and I never carve any anymore. I do have a portrait of my stallion's head I carved and mounted as a wall hanging. If I get my camera working I'll post a pic of it.
I made tooled belts, buckles and wallets back in the 1970's. I was never as skilled as you. Still have my tools and patterns. Last year I pulled them out and made a saddle horn cover for a child's saddle for granddaughter. The saddle horn had been chewed by a dog and looked very rough with some of the leather missing. (The pattern was traced on a leather belt buckle blank way back then and I had never tooled it, so I just went with it! Not the prettiest, but it is serviceable and she's happy.)
