POTW #11 - water marbling on my nails...

...pink + green is always a good choice :)
Hey sweeties,
time for another PolishOfTheWeek-post - today I present you my first tries in water-marbeling - its not quite perfect - but for the first time its quite okay :)
I made this look with these colors:
P2  232 shockful
P2 210 eternal
O.P.I. pink flamenco
and I used this tutorial from youtube:
its from pinkaddictive and I think its one of the best tutorials for water marble nails :) 
I have to get some practice for this technique but skills come with practice ;)
How do you like this technique - do you have some tricks and tips for water marbling?
