Ahh the collapsing world thing makes that island with the random tower on it make slightly more sense. Normally I'd suggest that the tower (and anything similar that you might also be building) was a bit too regular looking for something that was collapsing and maybe needed more broken looking edges but you're still just learning Blender which is a pretty daunting task on its own, that other kind of stuff can come later :)

_{though your non-planar quads are somewhat triggering my ocd XD}

In the screenies you were dropping on Discord I noticed you had a normal map, in the node editor in the shading tab you can either put it on the displacement tab of the material output to make it REALLY jump out or you might be able to wrangle a math node to make it a little bit stronger which might help the texture look slightly less painted.

The painting looks fantastic though, think you pretty much nailed that old weathered stone look :) and you generally want as few polys as possible to do the job you need them to do so image maps are great.

Remember there's a bunch of us that can Blender in the Discord, just ask if you need help XD I may not be able to help with rigging from scratch (I can do basic setup with basic bone drivers but I hate it) but I've gotten half-decent with Rigify which is one of those super easy when you have some idea of what you're doing things.
