All the art I find on the internet is done digitally and I don't know if doing it with pencil and paper reflects a lack of talent or things like that.
I ask this bc theres people who don't have drawing tablets, and it's nigh-impossible to draw with a mouse/touchpad on pc
There's absolutely nothing wrong with it, so go for it if you want to!
For most of my professional work, I usually start off doing the initial sketch on paper, before photographing it and finalizing it digitally, so there's lots of different approaches. None of them are wrong and all of them are right as long as it works for you.
If anything, I'd argue that some knowledge in drawing/painting physically is a great prerequisite for knowing how to use certain digital tools. Similar to how knowing how to play acoustic guitar before learning to play electric guitar has several advantages, but doesn't really work the other way, but that's another point entirely lol
It's also good to remind yourself sometimes that much art you see online actually is drawn physically, but if it's scanned professionally it might be so clear that it looks digital.
