This is the makeup I use to look more androgynous:

Skin care first (please see my skin care tutorial).

I line my eyebrows using an angled brush and the Romanced Eyeshadow Palette (w7) - using Romeo to draw a square around my inner eyebrow and lining the rest of the brow in Affair to produce a natural gradient and make the brows look less drawn on. I then top off Affair with the Brow Sculpt Kit (Body Shop), blending it into the centre to give a larger difference between the dark and the light and then top of with Affair again to help set the pencil. Press in the Technic Soft Focus Transparent Loose Powder (Technic) with a powder puff and sweep away any excess around the brow, leaving the brow looking white (this will set the brow and keep it on all day). 

Use the Romanced Eyeshadow Palette (w7) again and pick up Fairy Tale on a fluffy brush and press it into the crease of your eye - this will give a sunken in look to the eye, which is a typically more masculine look. Smoke out the excess around the lid to make it more natural. Add Masterpiece Mascara (Maxx Factor) to the top lashes, do not touch the bottom ones as it will instantly feminise your face, and curl them up to god. 

Define your cheekbones using the Revolution x Roxi Powder Highlight and Contour Palette Kit (Revolution or Superdrug). I suck my cheeks in and then draw a line where they dip in - these are your natural cheekbones and then your contour will move with you - but only contour halfway along the line and then buff out with a large fluffy brush. Contour your nose and forehead according to your face shape to make the contour seem more natural. Pick up Duo Blusher - 01 (w7) on the same brush and swipe across the tip of your nose and the apples of your cheeks (smile and then apply blush). Buff out. Add highlight on the tip and bridge of your nose, brow bone and you cheek bones using your Revolution x Roxi Powder Highlight and Contour Palette Kit (Revolution or Superdrug) and then buff to ensure the highlight is blended into your contour. Swipe off the powder on your brows.

Set the entire face using Technic Soft Focus Transparent Loose Powder (Technic) and buff out. 

Coat your lips in lip balm to make them look juicy and moisturised. 

General Tips and Tricks 

Contour in an arc - this masculinises a more feminine face.

Contour your temples and forehead - this gives a more defined look. 

Focus highlight onto the middle of your face - do not highlight your forehead, chin or cupid's bow - as this gives a more rigid and less curved facial structure which is typically a more masculine look. 

Darken your eye crease and follow the shape of your eye to make them more sunken in and less feminine. 

Draw on freckles (optional) but they are typically associated with androgyny. 

Avoid pink blush, it makes your face too bright and more feminine. 

Avoid mascara on your lower lashes, this feminises your face immediately. 

Avoid glittery, pale highlighters (such as whites and blues) as these give too much of shine and make your skin seem oily. I find gold and even light pink are optimum highlight colours.

Do a nice glossy lip.

Avoid large false eyelashes, but try using small ones to make them look thicker and fuller.
