Thought I would get a clarification; the wording made it seem like it was digitally painted
-- you drew it -- and using a filter could have caused someone to think misrepresentation on your part. Unfortunately there are a lot of people out there who slap a filter onto a photograph and say they drew/painted it...
In short, being "digitally done" no longer means just editing photos in Photoshop. I, myself, have used Photoshop for drawing purposes.
Some people, like myself, use the digital form for drawing, too. So "painting" can also mean like when you paint on paper, but using a digital program like Photoshop. Refer to the video below (and others like it). Not my favorite example, but it moves the point.
Best of luck!
