Polka Dot Mani

I sported this manicure last week and got a few compliments, so I decided to recreate it here...
I got the inspiration a couple of weeks ago, as I was standing in line in H&M. They had some posters in the cashier area and the models had something very similar on their nails.
For this one, I used Sally Hansen Complete Salon Manicure in Grey by Grey as a base, and Lavender Cloud for the dots.  I inverted the colors on the ring finger just for fun.
I used a dotter nail art tool for the dots.  You can buy it online, I think I saw them going for $3.00 in ebay, but if you guys can't get a hold of one, you can use stuff you have around your house like a toothpick, a bobby pin, or the fine point of a orange wood stick cuticle pusher.
It's a very easy way to spice up your nail polish, it looks great and it's inexpensive.
Now, the nail polishes... I ADORE both shades! They are super interesting and unique. What I don't like is the brush on these. It's rounded and thick, and it makes the application very difficult for me. The formula is awesome, almost opaque in one coat, but I always give it at least 2, just for peace of mind (I hate visible nail line).

Anyways, what do you think about it?  What other colors would look good together?
