Inkscape is for vector art, yeah. Great for design, not for like, painting.
Krita is pretty great for a free digital art app. But I used it for about a year and could never quite get used to it. I recently went back to Clip Studio Paint (with my perpetual license they do still honor), and my experience just improved so much. It was like... ah, yes, an art program that clearly paid people to specifically make the UI easier to use for non-programmers, what an underrated feature.
I secured a major promotion at one point in my life using inkscape to create a business logo for the company I was climbing. I learned all about vector graphics and how they scale seamlessly, and loved it and gained a new appreciation for logo design in the pre-AI days. I did eventually make it to VP position in that company before the great economic collapse of '09 forced 80% layoffs.
