I think you are quite masculine in general but I have a few tips to help you out.
In your last pic (sunglasses and red shirt) you do 100% pass in my opinion.
However, I imagine if you took the glasses off there would be a couple of things that would make you more feminine and you might not pass anymore.
Don't use eye liner. In makes you look feminine in your other pictures. Yes emo guys use it and get away with it because their masculine features override the feminising effect of the eyeliner. But for you, you are going for as male as possible so I would stay away from it.
Your piercings in the last picture (silver ones) are fine, but the large black ones in the other pictures are very feminine looking to me. I would not use those either. For guys, jewellery is very dull, plain and simple looking. Silver studs are ok.
Your wrist bracelets are quite female also. Guys never really wear anything on their wrists, unless it is a chunky gold chain.
Need to grow the eyebrows out. Your eyebrows look plucked which make you look more feminine (I want to pluck mine but i can't yet as Im still in male mode and afraid people will notice). Genetic males give their eyebrows zero maintenance and let them grow out whatever way they happen to.
I think you should probably keep your hair no longer than your chin. If you cut it short I think it would probably help. Not many males with long hair.
It's so much easier for FTMs than MTFs with transiton. You almost have to do nothing to pass, whereas we are *very* high maintenance to present as female.
Good luck!
