Why is my tip wear so horrible?

 I haven't put a nice big picture at the top of my post, because these nails just don't cut the mustard.

I have used models own magenta divine glitter with a china glaze black crackle topcoat. Even with tip wrap this just sucked back from the tips of my nails like chavs from a naked flame.

Other than this the mani looked amazing and would look great on a night out. I am open to any ideas.
