Trying to style a side-part with fine hair but looks flat

I've had this problem for months at this point. My plan was to style my hair in a presentable way while waiting for my hair to grow out more, but styling just feels hard for some reason? So far I've tried to style a quiff and the side-part, but it looks different from the people in the video that i'm following. I'm using the right products for my hair, and I see some differences in how it looks, but it still doesn't solve the issue i'm having. Any help would be appreciated.
