You definitely don't look like you are in your thirties, that seems too old to me, but the beard does make you seem a bit older I think.
When I make a guess about someone's age, I never consider the beard because even a 18 year old guy can grow a lot of beard, your body is like an adult body at 18, I never consider beard when it comes to guessing someone's age, but the pose, the angle, things like that can cause me to guess the age wrong but not beard. Things like the angle of the pose have more to do with guessing the age wrong than beard. It is my opinion
i mean it looks fake it looks more real on this larger one youy posted somewhere else http://www.kizlarsoruyor.com/nasilim/q3130921-tipsiz-miyim-cirkin-miyim
