Pink crackle on bright blue nails

What about something blue for this Friday? I've got one picture to show you and it is edited on two nails which you will notice. Archive again. So as you can see it's a nail art with a pink crackle diving the nail.

 Polishes used:
HM Nail Polish - Blue my mind
Isadora Graffiti - Masterpiece Pink
Sure Promise (black)

Do you think this a good use for crackles you think? I'm ambivalent, maybe on longer nails?

Isadora Graffiti masterpiece pink nail art

Isadora Graffiti is old news, but I like the pink "masterpiece pink". However in this combination I don't like it that much. Ended up painting black lines with Sure Promise and putted on black opaque star rhinestones on the accent nails. 

Have to confess that I actually don't know what nail polish I used as a base, it seems blue. Or a very thin blue shimmer over a black? Can't remember.
