Rebuilt Blender Skills From Nothing in Three Days — 4K Texture on a Budget Laptop

Creating and texture painting from scratch a realistic mushroom with 4K texture on a laptop with 8GB RAM and no GPU in Blender. I re-installed Blender 3 days ago after over 10 years of disuse and little success prior, and was doing other stuff during those three days that took much of my time — so the skill pickup is pretty incredible. Plus I'm battling my own not-so-hot fine motor skills. Running this alongside Emperor Black.
