My first work in Krita, also just learning to draw with a tablet (some basic wacom bamboo).
Sketched and colored/painted compeletely in Krita.
Not really happy with the brushes, cant find brushes that i like, probably not a problem with brushes but with me
Gotta keep experimenting, don't know a fraction of capabilities of Krita yet, also drawing on tablet is still awkward but getting there ...
Still, tried some other programs, but Krita feels most "comfortable" so far.

You put your own image website location in there, then check it with the Preview button.

For larger images, you can post a link to an image hosting website or a file sharing service.
