Looks really nice and I do hope you’ll end up submitting it to the marketplace; there’s definitely room there for more great asset packs.
If I would have to give feedback on something then maybe the ground cobblestone texture looks a bit too flat for my taste, so I would either try to increase the normal maps bumpiness or try to do parallaxing for it. I’d personally try to add a bit more randomness as well, but I don’t if the asset pack really requires that so much.
