Let's say I want to draw/paint things like this: 1 2

Think black/death metal album covers, medieval renaissance, dark/sci fi scenarios.

I know this takes years of practice and I just want to do these as a hobby.

I am just lost to where I start. Just pen and paper and focus learn how to draw people first? Is there any online courses/resources?

The second thing is I don't want to spend money so I won't learn to do these with oil or any real world material. If I do commit to the hobby with pen and paper, I will go to digital (drawing tablet + Linux/krita) and stay on that forever.

It's the same with guitar. I play guitar for years and I'm settled for life with a nice guitar + mid priced digital pedalboard with nice effects/simulations (ampero II stomp) and a 1x12 flat speaker cabinet. No more purchases.

If i have a lot of acrylic on canvas paintings and I want to produce prints to sell, where do you make the prints? Local Kinko's/staples?
Clear plastic bag or no? Brief artist blurb at the back? Post card?

Have you ever bought a print? What made you want to buy it or what stopped you, and what would have made it go from no to yes?

Where do you share the art that you make with the world? Do you use a social media site? A personal website? Do you keep it all to yourself? Is your art something that can't be shared online so easily?

Just curious. I've been trying to understand watercolors better. What I love about watercolors: so much expression, so much freedom. It also seems like a uniquely frustrating medium; understanding how much water is needed, how water reacts with certain papers, different types of brushes, etc. (I should mention it's the only painting I do, so maybe this stuff isn't unique to watercolor.)

Curious if there's any other watercolor enthusiasts here. Care to share your experiences, or tips for a novice?
