Good thing you're trying to improve your mental state. Wish I could do the same but I'm trying to grind out my stuff like crazy. I've experienced burnout but I know what awaits me if I don't work on this stuff (Retail and misery). I don't have the luxuries of a wealthy family, good education or any other perks a lot of people online seem to have. It's either this or nothing. Sad, but it is what it is.
As I said before, Renpy is incredibly easy to use. If you translate your comics into renpy then upload it to certain sites; F95zone, itch, steam (if you got $100 to spare). You would get much more exposure. TK17 is just not suitable for comics outside of this site, people demand state of the art visuals mostly and yeah, people have done amazing work with TK but there is a limit. For instance, this engine will never have ray tracing. Yet DAZ, blender and even Unreal now has. It's not a minor point either because ray tracing is what makes things photo realistic.
There's no harm in giving it a try, just go to the renpy site and download a build. Watch one video and you'll learn how simple it is to get started. I see you're also capable of graphic design so it wouldn't be an issue creating titles / UI. Then again you can use the default stuff. Just choose your most standout characters that have gotten the most attention on here, and have them be the lead. Like Willow, she'd be excellent for a slightly gothic story.
Also expect criticism, and maybe even A LOT of criticism. But it's the only way to see what's wrong in your stuff and improve.
