This might be quite a long post, but I'm going to outline a kind of step by step thing, so hold tight. I'll try to be as helpful and to the point as possible.
It does not look as if you are wearing foundation. Bishounen characters have clear, dewy skin. I suggest concealer, then a pale BB cream (something like Missha or any other Korean brand), then a pearlescent powder for the base.
Your eyebrows are the colour of the wig, and they are too long. Eyebrows tend to be darker than the hair colour. I would suggest using a brow powder and then adding some of the red (to match the wig) over the top- but not too much, otherwise you'll look like a clown.
An important thing to note is NEVER draw your eyebrows on, which you have at the front. Only make corrections. If the character has straight, angled brows, carefully fill in the arches with the brow powder. Brow powder can be bought in a multitude of places, and brands like Etude House and Canmake make some really good ones.
As you will be wearing pale foundation, brow powder is probably the best thing to contour with. Do it very lightly, and follow some tutorials if you're not sure. You want to have a steady hand, though, or you'll look horrendous. Remember to highlight, too.
Eyes are the focal point of a face, as that is what people look at first. I noticed instantly that your eyeliner is too heavy and gloopy. I cannot stress enough how important the eye makeup is for a cosplay.
You'll need a non-smudge eye pencil, gel, or black powder eyeshadow (I think you can get black powder eyeliner, too, but I don't know how obtainable it is). To apply it, you will need an angled brush. I suggest watching a YouTuber called zWinnieyap, who does lots of anime eye tutorials. You can pick the one that is suitable to your character. Another thing is that male eyes will need some kind of dark brown and a kind of dusty burgundy at the outsides, blended fully but still retaining a sharp, boyish look.
Circle lenses are optional depending on your eye colour, but fake eyelashes are NOT. You will need some like these for the upper https://img0.etsystatic.com/001/0/57...66570_sfso.jpg
and these for the lower http://www.ebay.co.uk/itm/Koji-Dolly...p2054897.l4275
I'm not endorsing Dolly Wink or anything- I've never used them. You'll just need something similar.
Of course, you will need to highlight the area below your brows and at the inner corner of your eye.
Lips are simple. An ulzzang-style gradient lip in a coral-ish pink shade (achieved by covering your lips with foundation, then blending lipstick out from the center of your lips) finished with a clear gloss will do the trick.
Always apply your makeup in a well-lit area, and always clip your hair out of the way.
Do not wear your wig while applying the makeup.
The night before, the moment before, and directly after wearing makeup, wash your face thoroughly with hot water and face soap, then rinse with cold water. Moisturize with coconut oil or something chemical-free.
A q-tip dipped in coconut oil can clear up any mistakes (yes I love coconut oil).
I recommend Korean brands for cosplay makeup.
Fake eyelashes can be purchased in packs of up to 20. Here's a link to some like the upper ones I posted an image of earlier http://www.ebay.co.uk/itm/10-Pairs-B...em25a294 4a40
If you have any questions, I will be happy to answer any.
