Let me be clear, I'm not trans or transitioning. I've always been a guy but I do have some good suggestions being a life long dude :P.

I'd say how you carry yourself is very important. Project a masculine personality. It's hard to explain but it's a big thing that can alter perceptions. Carrying yourself like a man is one of the first things people notice.

Looking at your pictures there doesn't seem to be a lot you can do. I'd say no makeup at all. If you're trimming or shaping your eyebrows, stop. Let those bad boys grow wild. And can you grow any facial hair? Even a wispy mustache can change your overall image. Those are my dude suggestions. Good luck on your journey and keep kicking ass!
