Will keep this short. GIMP isn't bad. But it may actually be better to include PhotoFlare instead. It is still advanced, but manageable. Or just add PhotoFlare to the package of included applications in Zorin? Just some feedback there. Also, as a heads-up to the Zorin Group, Krita doesn't work right in Zorin OS. When I open an image using the main screen that pops up at the beginning when launching the application, Krita suddenly shuts down. Something to investigate, I suppose.
