The problem is your dressed wayy too formally in all of your pictures. A vest, suit and tie? Have you heard of a t-shirt? Sure, I like formal clothing and all. But as a default picture it basically sums up yourself quite briefly for an external viewer. You look like you need to loosen up a bit, pull a funny pose, wear some casual clothes. You know, be a teenager. You just look a bit uptight is all, I don't like it.
Basically, here's an example of what I'm talking about. Compare your DP to my (not current) dp. A photo taken on a great night, relaxing with my best friend, drinking some rockstar, usually I'd pull a silly pose like my friend is but I was midway through a drink and just wearing normal clothes. It doesn't make me seem too formal or too casual, it's just nice.

Or, even yet, another older DP. A simple webcam chat with a friend, being silly, wearing glasses and poses like a shocked homo whiost my friend does a quagsire impersonation. It shows emotion and socialisation, normal characteristics. I dunno, Maybe I'm just ranting shit but I really dislike the options tbh. Pic below.

Go for something less forced. My 2 cents.
