I had almost 400 matches matches on Tinder and found my girlfriend there as well (surprisingly...) with only two pics.
Here's my advice:
Your pics scream an air of depression. Take pics in a bright location (yes this does matter, especially for girls) as pics in a bright location will naturally make you look happier, content, etc. Perhaps try something outdoors.
Moreover some of the pics look like you are a thug or the type who sprays graffiti on buildings. Girls do not like this...
There's a difference between an all around successful badass/risk taker that every girl admires and some punk who scribbles code using Sharpies on the side of a building.
Lastly, put up a pic of yourself in a suit, seriously. Or perhaps you at work. Your pics are screaming someone who lives in basement. I'm not saying you live in a basement of course but your pics make it seem like you do. Girls like men who are driven, passionate, and goal oriented.
Didn't mean to sound like a jerk of course, I sincerely want to help.
First pic the guy behind you ruins it Second pic looks like it belongs on a christian dating site Third pic looks like a mugshot Fourth pic I'm not touching
Tinder is a superficial app so you gotta be superficial. Take pics showing off a cut bod, get pics of you doing hobbies. Got female friends? Use them for social proof to show that chicks can stand to be around you.
You won't get many matches, period. Unless you look like a douchebag male model (either hipster or clean style) with filtered main picture and/or your pictures suggest you are very wealthy. Girls are a lot more picky on Tinder than they are in real life (because they get dozens or hundreds of matches per day and you don't get to use humor, intelligence and body language on Tinder), that's just the way it is. I don't think most girls even know about the disparity so they'll give you useless advice like "write a better bio" or "be more creative at messaging". Of course local population density is also a factor: you'll get more matches in Manhattan than rural Kentucky. If you can get one per week to actually stay in a conversation with you you're already doing splendidly.
Having said all that, you can improve your pictures: find the angle that works best with your face, avoid grainy/blurry pictures, take pictures outside and in non-everyday locations.
The pics you took are just not good, period. Not saying you're hideous, they're just bad pics. Try to grow a beard too. I feel like clean shaven guys are doing themselves a disservice by not having a beard?
