Tinder is a very visual medium. You should take a look at your photos and make some adjustments.
Make sure your photos are fun. If your photos are boring, with you just basically looking at the camera and nothing else, they can turn people off.
Use your photos as a vehicle to showcase your personality and lifestyle. Be fun and unapologetic in them. These kind of photos tend to have really good results on Tinder, giving you the best opportunity to get more matches.
