yet another mockup (greenish one)

hey guys,
since im a very big fan of ubuntu, i decided to create a mockup on my own for the upcoming new ubuntu version hardy heroin. I've worked on it about 12 hours up to now and I would highly apprecieate it, if you told me whether it's worth continueing the work on it or not:
