Manicure: Ombre nail art with O.P.I. Melon of Troy, Didgeridoo Your Nails and It's All Greek To Me nail polish

I haven't been using O.P.I.'s Melon of Troy much, as I prefer deeper colours and cremes. Though it is a spring colour, I thought it would do for the upcoming week, so on it went. One coat later, a bit streaky, and too pale for my liking.
I can never leave well enough alone as usual, so I was looking for other things to do over it. My Konad stamper is MIA for the last few days, and I didn't feel like the nail pen or shatter. So it had to be my second-ever ombre.
I picked Didgeridoo Your Nails? and It's All Greek To Me. That was a mistake, as a novice like me can't bring out the difference between these colours through ombre. But then I'd probably mess up even blue, yellow and red.
Anyway, the results are here for all to see. How do other people manage to bring out the difference between very similar colours through ombre? I applied NYX Red Glitter over the "ombre". I don't know if the ombre effect even shows up!

Of course, I can never do ombre without getting polish all over the place and myself, so I'm going off to clean my upper lip and left knee.
