Do I have a canthal tilt , cheekbone issue , flat look (young male) ? (photos)

You are fairly young to be having this issue de novo. Have you had other facial surgeries/trauma or even dermabrasion? While your actual canthal tilt (line between inner and outer corners) seems to be neutral, there is no doubt that when you relax, there is more white of your eye that shows especially on the right (sclera like show). If this is causing you to change your behavior and be self conscious about it, small things can be done to both tighten up your lower eyelids. Long term, it is helpful to have cheek support for your lower eyelids. Seek an in person consultation with a board certified plastic surgeon who deals with eyelids and faces. 

It is difficult to tell from the photos submitted but it they right eye appears larger, either because the right eyeball is more bulgy or the right lower eyelid is retracted (lower).  Best to see an oculoplastic specialist for evaluation.

You need to have a complete history, exam and labs. The results of these will determine your treatment options.
