Mirin' masculine head shape and jawline in pic 1 especially. And you're 156 at 5'6"?? Unless you're muscular and I'm being misled by your weight, I think you would make great facial gains by dropping 15 pounds / getting lean. If you're intimidated by the gym (like me), I recommend a home gym (looks like you've got the space, all you need is a power rack and a barbell pretty much) or go to the gym at 1 - 4 AM.

I am pretty good at taking selfies so here are my tips. I included my photo from photofeeler that utilizes this tips that got rated well (albeit by young women, who I know are outside of your targeted demographic).

• Take selfies in front of an open window that allows sunlight to shine on your face (but not so much that you squint from it). This is your main issue: notice the yellow tinge in all of your pictures from indoor light. I legitimately think this will make a big difference.
• You have clear skin, so appearing pale is not a bad thing.
• All of your pics are fairly blurry, which may again be because of lighting or could be an issue with your camera quality. Get a better smartphone or see if you can rent a nice camera
• Taking pic with selfie stick is fine, tripod may be better though.
• Notice the reflection of light in your eyes in pic 2. This is good: it looks like there's a spark in your eyes and makes you a little cooler looking. Especially try to replicate this in front of a window with natural sunlight.
• Try to smile with mouth closed if you can get dimples, and then you've got to really try smiling with your eyes. Smiling with your eyes is a difficult concept, but it boils down to squinting very slightly like you're laughing. I think you're halfway there in your pics, the smiles look fairly genuine, but keep trying

Here is my pic using some of those tips above (though you can't see my eyes). I'm not Chad - I've put up pics on photofeeler before and gotten 30 - 40% because I took them indoors in shitty yellow lighting.: http://i.imgur.com/YPdMlaA.png
