This is very simple. Here, you have to describe your own face-elaborately!! Try to make it lively and amusing and be honest. Mention the colour of your iris, hair and of any other colourful facial feature. You might add your hair style/length and everything else. Also, if you can try to relate the shape of your head/face to something-anything hilarious!
**Always remember-we probably will never actually meet and therefore a little imagination won’t hurt. Get my intended hint?!**
Calvin : You can't just turn on creativity like a faucet. You have to be in the right mood.
Hobbes : What mood is that?
Calvin : Last-minute panic.
