Hello and welcome to the forum @dino107!
Iām pretty sure that all the images you showed as examples, can be painted/drawn with Krita as it is today. That doesnāt mean Iām capable of doing it.
I suggest you visit the forumās own gallery, for example the Finished Artworks Category, you will be surprised what all is possible with Krita. Check out RoseRedTigerās āA series of elemental Dragons in different rainbow colors in no particular orderā, they are modern Dinoās so to speak.
To your comment about untalented artists, I can only tell you that Krita will not paint for anyone, everyone has to do it themselves and even supposedly āuntalentedā people can learn to paint, itās like most things in life, school, profession, you just have to practice, practice, practice!
And the things in your question that go beyond the painting part, that need a feature request, like linking to other software for example, I would like to recommend you to read the manual part about āFeature Requestsā, a recommendable article - at least I think so.
