hmm...... as far as it being a screenshot, and copy rights applying to that, I dont think so. This is nothing like the base template which was a screenshot. The only thing of the original that might be present would be the colors in the window in the background, as for the remainder, not a single line, color or pixel is from the original.
As I clarified, its a digital method I use sometimes which is akin to tracing a drawing by placing a thin paper over it, the difference is, I dont use paper or tracing, I do it digitally.
So, this piece, started with everything I painted digitally, and I only kept the colors in the window in the back, because they looked beautiful.
I still think the category applies, it wont be a 100% fit but then my method is a personal discovery, a label for which I dont think I would find here except may be mixed media or something, which doesnt clarify the method the artist might have used. This chosen category however reflects that more aptly, in my opinion that is.
