Looking at the image by Russian artist Vladimir Kush, ask yourself: do you see the sky at first glance or do are you drawn to the lips?

Some people might spot a pair of lips at first glance, while others might notice clouds in the sunlit sky. 

If you saw the clouds first, it means you don't like to let your guard down in front of others and are constantly watching your steps when interacting with strangers.

You've got a cynical side but when you do build rapport with people fairly quickly - it's just hard to earn your trust.

But, if you see the red lips first - you're kind-hearted and go above and beyond for others. 

You are the type to help out a stranger whenever the need arises and are sentimental and upbeat.
