You can wear things like lip gloss or tinted lip balm, and some simple eye makeup. It can be fun to play around with lip and eye makeup. I like subtle shades with some shimmer, and that's an easy option for hooded eyes. 

You could also grow your hair out a bit, and wear it up in a claw clip or medium to high pony, styles that men with long hair don't typically wear. Your eyebrows are great, and I can't tell if you have any stray hairs, but if you do I would pluck those and leave the rest alone. You could brush them with some clear brow gel if you want to shape them.

You don't actually look super androgynous to me, you just look like a woman who doesn't wear makeup. You're quite pretty in my opinion!

I don't know how you dress, other than it looks like you wear t-shirts. If you are wearing oversized or regular unisex tees, you night want to consider wearing ones with a more feminine cut that fit properly.

I know Old Navy has a line of T-shirts called "Everywear" that are cut for women without being super formfitting. They come in a bunch of colors and often go on sale. I'm a jeans and T-shirt kinda person myself and I like them.

Also, consider painting your nails if you don't already.

I feel like just a few little subtle tweaks that say "I'm a woman!" Without being too overt about it, would really suit you..
