(now the fail comes, because I changed my account and forgot to log out my old one last time. so, old Nephilie is writing now)
Well, I don't think you need to do something really ugly if you're not in the mood - just give your roses some thorns. It's like Mona Lisa - she's famous like hell and people call her beautiful, even if she doesn't have eyebrows.
As I said, I know your paintings for many years and I know, you're the one to paint the beautiful things in the world. I only miss something like contrast and dynamic based on more hard lines. Prettiness is not a thing only for round shapes
