well its a rubies, and i knwo how difficult they are to work with!
i liek the stripe thing in blue. very nice and original. also did you use an airbrush? looks good.
kinda hard to tell detail, these are webcam pictures? the only thing i woudl say is if it were mine, id try an re-shape it somehow, and repaint the red boxes. they are a bit crooked and not semetricla enough. other than that, looks pretty good!
