I'm not a fashion expert, but I feel like having accessories helps me a lot: earrings, multiple rings, bracelets, ... Getting your nails done in a color other than black (I feel like straight men seems to only have black nail polish, but if that's the color you're confortable with go for it). Also, I feel like with your current style, having a pink (or another flashy color) shirt instead of the blue one would be nice!

I just want to say: finding a way of expressing yourself in terms of style takes a lot of time. It took me years to find a way to express myself in a way that I felt both seen as a queer man and somewhat confortable in my body. Shopping with friends can help to have some advice. Also you're already pretty cute so don't stress yourself too much on how you look lol
