I know it's hard seeing your work stealed over but keep strong, we know who you are and love your work. People doesn't seem to understand how awesome it is that you share your work without watermarks or anything like that but we do. Love you! Now go make some bigger signature on your paintings and frame the first one bc it has now a raw energy that deserves to be preserved.
You don't have to feel bad at all, because I do think it looks better. It is actually exactly what ARTPOP is all about. You can even see it on the cover; the font is very "cut" apart. Imperfection is the new art form.
