A little F.A.Q. and some important links!
I use a Wacom Mobile Studio Pro with Clip Studio Paint for my big illustrations and comic pages. Additionally, I use an iPad 7th gen with ProCreate and Clip Studio Paint for "drawing-on-the-go", as well as my trustworthy sketchbook+pencil!
Not at the moment, sorry! With the kind of work I do (science) I don't have enough time to work on my own art as it is, let alone do art for other people :'D
Yes you can! Please tag me if you do!
Absolutely not. You can not upload my art anywhere without asking, not even if you credit me. Reposting art is incredibly rude and usually done in bad faith (e.g. to gain views/likes/upvotes/followers on sites like Reddit and Instagram).
Instead, you can of course just share the link to my art on sites like Reddit, and on Twitter you can retweet my art posts. As for Instagram, I would rather not see my art there at all!
You are a fantastic human being, and I love your work! Keep being awesome!
