Your hair will look different when you don't shower after a few days because of the oil build up in your hair. Your crown looks fine to me. Take a shower then post pictures with your hair wet and dry after the shower. Your hairline looks good too! If you feel like you are losing more hair daily, then I would suggest going to a doctor or derm to see if you do have male pattern baldness or not. If you do have male pattern baldness, then your best option to help maintain your hair would be to use propecia or finasteride. For now, if I were you, I would just monitor your hair for a couple months and see if anything changes. Be sure to take pictures each month. Good luck.
