Hey howdy! I'm Leech, my pronouns are e/em, and I'm a Canadian illustrator, storyteller, novice coder... a lot of things. I'm a lot of things.
I use Krita, which is free, and the ugee 10 inch m808. That link isn't an affiliate link, it's literally just the website page for it.
My website is coded with the help of various online tutorials, but my main reference point is w3 schools, and this site is just very basic html and css. Images are hosted on the website catbox.moe so I can save website space. I can't give you any bespoke advice for how to do something similar, just look online! I believe in you.
